1.)I can tell that the effort arm and the resistance are of the levers varied depending on where the fulcrum was. Either the effort arm or the resistance arm required more weights.

2.)You might be able to develope a generalized model for solving a problem by testing out different scenarios.

3.)They might be effected by there being so many different scenarios to account for in a trial and error strategy applied to real considerations.

1. The same methods applied on either side if you reversed the starting data the outcomes would follow the same pattern.

2. YOu might be able to develope a generalized model for solving a problem by testing out different scenarios.

3. There are so many scenarios and obstacles to account for in a trial and error strategy applied to real world considerations.

1.The relationship between the Effort arm and the Resistance arm of your levers are that on a first class lever both of the of the sides took the same amount of washers which means the data was duplicated.

2.You can develop a generalized model by making a first class lever.

depending on where the weight scale was and how many washers there were, the relationship between effort and resistance depends on the pattern effect it will have.

1.When ever the fulcrum is closer to one end the other side is heavier.

2.You can try to use different senarios to come up with different answer to the balancing method.

3.Trail and error can help you choose different methoes and you will have many conclusions.

1.)The relationship between the Effort arm and the Resistance arm of your levers takes the same amount washer to balance each side if the falcrum is in the right postion of the ruler.

2.) Finding out how to balance each side witout moving the fulcrum and collecting the data of the ruler and amount of washers.

3.)This might be affected by the real world because situation like kids playin on a see saw relates to this experiment.

What can you tell me about the relationship between the Effort arm and the Resistance arm of your levers? Be detailed.? the effort arm andresistance armworked together to get a balanced force. How might we develop a generalized model for solving a problem?a generalized model would be a first class lever. How might trial and error strategies be affected by real world considerations? There mightbe different scenarios and or obstacles.

1.you have to keep moving the fulcrums so that the effort armand resistance arm could balance out.
2.you can do it by trying out different trials.
3.the are a lot of diff trials people go through in life in by changing the different fulcrums is the same to changing problems to balance the problems out.

06/28/2011 06:57:35

1. I can tell that the relationship is that the loads that had the least usually outweighed the side with more loads if the fulcrum was close to the end.

2.You might be able to develop a generalized model by testing diffrent trials to find a relationship.

3.I dont know how trial and error strategies can be affected by real world considerations.

 

Tiara 1

06/28/2011 06:57:37

1.I can tell you that the E and R arm varied depending on where the fulcrum is. The Effort or resistance arm will require more washers than the other.

2.You can make a generalized model by drawing a first class lever.

3.I don't know how to answer this question.

 

mackenzie b. 1

06/28/2011 06:57:42

It really was based and depended on the amount of washers.

Come up with different ideas and group senarios.

You just have to realize errors are liable to happenig and they might help you in your expriement just work around them like in real life.

 

Montell

06/28/2011 06:57:52

1.The shifted both ways depending on where the fulcrum was on the ruler. Sometimes it was on the effort arm side or the resistance arm side it flipped.

2.You can find out some different ways by figuring out some ways of to multiply and divide in some way.

3.it can probably come use for when your balancing different things in a store or your money.

 

Timara W 1

06/28/2011 06:58:07

1.I can tell you that the relationship between the Effort arm and the Resistance arms of lever have many patterens. Most of them have to do with factors of a certain number. examples ; if its 8 washers that it will be two on the other side. Then 6 and 4 , its all about factors.

2. I dont quite know how to answer this question but you might have to test diffrents ways on this trial.

3.They might be effected by the real world becasue with out errors, how will you know if you're ever right.

 

Dyeshia S.1

06/28/2011 06:58:18

1.The relationship beween the effort arm and the resistance arm changed depending on where the fulcrum was positioned.
2.You can devolpe a generalized model by testing differfent numbers.
3.trial and error stratergies might be effected by any complications.

 

Lauren P. 1

06/28/2011 06:58:22

1.)The relationship between the Effort arm and resistance arm seemed to follow in the same pattern each time I applied the washers on the ruler.

2.)You could develop a generalized for solving the problem by making a different lever.

3.)Different obstacles apply to the real world considerations and sometimes may not be applied to the trial and error strategies

 

Nia V1

06/28/2011 06:58:28

1. On most of the trials they used the same amount of washers, and if you move the fulcrum to the opposite side of were it was it will use the exact same amount of washers.
2. You can get alot of different results during your trials.
3.There are alot of different trial results and there was some positive outcomes and also negative.

 

imani r 1

06/28/2011 06:58:30

1.the longer the effort arm, the more weight is required on the resistance arm to either balnce it out or overcome

2. drawing a picture with both the effort arms and resistance arms the same length with the fulcrum in the middle

3. trial and error is a good method because it gives you a way to come up with a solution while figuring out what doesnt work

 

Sydney L.1

06/28/2011 06:59:17

1. The effort tries to push down on its side to make the other side go up, causing the other side of the ruler to try to resistance going up.
2.I don't know
3. In general trial and error helps us know what we can do to help benefit use. Like you have to go through mistakes in order to perfect it.

 

Janice B....1

06/28/2011 06:59:22

1. The relationship between the Effort arm and the Resistance arm would be depending on where the fulcrum is placed and the amount of washers that where used. For, example when me and my partner moved the fulcrum father to the LE part we need more washers on the LR side then the LE side.

2. You can make one of your on lever with just a pencil, ruler, and coins and try different solutions.

3. You can find that some of the real world conditions are unable to succeed with specific scenarios that are tried.

 

Jasmine T. 1

06/28/2011 06:59:27

1.) When we had the effort arm at 8 in. with 2 washers and the resistance arm was 4 in. with 6 washers, and another trial was the effort arm was 10 inches wiht 4 washers and the resistance arm was 2 in. with 6 washers, which shows if you go up 2 inches then you have to add 2 washers to the side that went up to inches.

2.) You can develop a generalized model for solving a problem by doing trial and error expireimentations.

3.) Trial and error strategies can be affected by real world considerations by applying how you know that you can learn from your mistakes, or when you do something and you know it't not right then you can keep trying and trying until it's right.

 

Adrienne D.1

06/28/2011 06:59:29

1. I can tell that whether the lever was balanced or not, it depended on where the fulcrum was and how much or how little the effort and resistant there were.

2.You can develope a generalized model by trying different things out that could possibly work.

3. Trial and error strategies are affected by real world consideration because they can help you find something that can work by trying other things that you may not know what can and cannot work.

 

Deja A. 1

06/28/2011 06:59:33

1.I can tell you that the relationship between the two arms varied based on where the fulcrum was and how many washers were on each side. At one point the same amountof washers were on each side so each side was balanced.
2.You can develop a generalized model by making different levers and different snenarios and maybe a different amount of washers.

 

Sydney O.1

06/28/2011 06:59:58

1. The relationship between the effort arm and the resistance of my levers would change based on how the fulcurm was placed.

2. I don't know how to answer this.

3. Trais/errors might be affected by any complications.

 

Shelby M 1

06/28/2011 07:00:26

1. I can say that on the balance the R and the E don't have to have the same amount of washers on each side to have an equal balance.
2. By trying different tests and situations of things you can get a better generalized model.
3. Trial and Error situations can effect our every day real life because there is not always the opportunity to guess on some situations which will sometimes lead us to trouble.

 

Natasha M.1

06/28/2011 07:01:02

1.Depending on where the weight scale was and how many washers there were, the relationship between effort and resistance depends on the pattern effect it will have.

2.We can develope different scenarios.

3.I don't know the answer.

 

octaviah j.1

06/28/2011 07:01:32

1.It seems as though when the resistance and effort are similiar, the length of the resistance turned out to be higher than the length of the effort.I also saw that even when the resistance and effort is different then the level of resistance is still higher.

2. We could develop a generalized model for solving a problem by testing out different answers and performing different tests.

3.In real world considerations trial and error is the best way to solve problems because if it doesnt work one way most likely it will work another way.

 

Tiara 1

06/28/2011 07:01:38

1.) The relationship between the effort arm and the resistance arm of the levers are that depending on the weight either the effort or the resistance would weigh much more.

2.) You could develop a generalized model for solving a problem by making various trials. By doing the various trials will give you a numerous of results. Depending on the results they would either be similar or different. But if your results are different it will show the change in your results and how good the trials went.

3.) The trial and error strategies will affect the real world considerations because being so many different strategies gives you different results.

 

1Caneka

06/28/2011 07:01:41

Based on my information I can tell you that the relationship between the Effort and the Resistance arm of my levers were very difficult to balance out.

We can develop a generalized model for solving a problem by everyone working together and coming up with a plan.

 

Daeja C. 1

06/28/2011 07:01:43

1)Through experimnting I came to the conclusion that the closer in length size the two arms are the smaller the amount of rquired effort will be needed to lift the load. As the effort arm gets shorter, more effort will be required to lift the load.
2)If we kept doing more trials we could possibly find a pattern and base a model from there.
3) Some problems can be solved effectivly with trial and error like math problems, recipes, etc. More elaborate issues like pregnancy, marriage,etc wouldnt. I belive the simpler the problem the more affective trial and error will be. When you bregin to add emotional factors and more complex things,trial and error wont be so affective.

 

1. Anthony

06/28/2011 07:02:11

1.Based on my data I can say that it was more effort than resistance




2.We can generalize a problem by making them balance out

If you add the number of resistance to the number effort and subtract the sum by 2 you should then put the fulcrum at the number you got when subtracted and it should be even.

 

DeVon G.

06/28/2011 07:49:51

This experiment was pretty cool. The numbers really were not different if the fulcrums were close together. The experiment didnt take much time at all. I cant wait to see what all my results mean.

 

Stephan Mcintire (2nd Hour)

06/28/2011 07:50:07

Well, I've noticed that if you add the number of RESISTANCE to the number of EFFORT and subtract the sum by 2, you should then put the fulcrum at a number(not exactly on the number but close) that you had as your final answer

 

Erica P. 2

06/28/2011 07:51:09

1. The relationship between the effort an resistance arm seemed to be dependable on each other and the fulcrum. If we move the fulcrum closer to one othe arms then on the lever one of the arm's will go down unless you hve the fulcrum in an even spot or n even amount of washers on th arms.

2. We can use diagrams or simple experiments.

3. Trials or errors will let u know which one is more accurate and have a understanding workable conclusion.

 

jenellep.2

06/28/2011 07:51:26

1.)Based off of my data I can tell you that the resistance and the effort is based off the fulcrum. I say this because if the fulcrum was in the middle it took an equal amount of effort to get the lever to move.
2.)To solve problems it would probably be best to leave the fulcrum in one place and do multiple test at a time with the same fulcrum. Another thing you could do would be to change the fulcrum and keep te same effort and resistance numbers.
3.)They might be affected because the data may not be accurate.

 

jamilas2

06/28/2011 07:51:35

1. effort arm is trying to make the change but the resistance is trying to keep it from changing.
2.you can do many trials in diffrent ways
3.it tells you what works and dosent works what you should and should not use.

 

Danesha J. 2

06/28/2011 07:52:08

1. Effort arm is when you apply the force when usinmg the weights to make the lever balance out and the resistance arm is depended on the effort arm order to move.

2. We might develope a generalized model for solving a problem by solving differnt models or testing an experiment.

3.Trial and error strategies could be affected by real world considerations because it can guide you by letting you know what is wrong and right.

 

tyra W.

06/28/2011 07:52:48

The relationship between the Effort arm and the Resistance arm of your levers are that were weren"t difficult to balance out because we werent using the middle of the ruler.
During this expiremnt I came up with the conclusion that if the effort arm had more bolts the resistance arm, the resistnace arm will over take the efoort arm.

 

Zachary M 2

06/28/2011 07:52:59

1.The relationship between the effort arm and the resistance of my levers would change because of how the weightswere layed on to the lever

2. You should put the fulcrum at a number but not on exaactly on to the number

 

marcus davis

06/28/2011 07:53:18

We noticed that the less washers on the restinance arm then the more yhu have to have on the enforceing arm

 

LaurenR.2

06/28/2011 07:53:31

1. The relationship between the two is based on the position of the fulcrum. Depending on where the fulcrum is placed detrimines how high or low the resistance and effort are.

2. To answer the problem we can try this actvity in a different scernrio or trying to see when the lever is balanced. If we do this we can find a possible pattern.

3. By trying this actvity in the real world, this can be a big detail when building a bridge. When building a bridge they must use trail&error to make sure iit will become balanced.

 

Janeice.B

06/28/2011 07:54:16

1.) I can tell you that between the Effort and Ressistance is that like eahc time you try to change the levels of it mostly the resistance was making it go right

2.To create a generalized problem is that we can do more and more trials and possibly we can find a pattern between the Effort and the Resistence

3.It can tell us what we did wrong and we can work on it again to gte it much better.

 

Timera Brmlett

06/28/2011 07:54:21

1.the realtionship between the E and R
are that depending on the weight either the effort or resistance woukd weigh much more
2)If we kept doing more trials we could possibly find a pattern and base on a model
3.) The trial and error strategies will affect the real world considerations because being so many different strategies gives you different results.

 

JanaeI2

06/28/2011 07:54:31

1.My conclusion to this experiment is that when the leverage was closer to the resistance the resistance was stronger and when the leverage was closer to the effort the effort was stronger

2.You can develop a generalized model for solving a problem by doing different test and making them balance out

3.Trial and error strategies help with the real world because when you dont know an answer you can eliminate the wrong answers

 

Naomi J 2

06/28/2011 07:54:59

1.The effort arm took a lot of washers to fully change the balance of the ruler, whereas the resistence arm didn't take many washers to change the balance of the rulder.
2. By doing multiple experiments and change things about the experiment that is not changing.
3.You may try things in the real world that you dont succeed at but if you change certain things about what your doing you can eliminate your chances of error of failure but sometimes this may not work because some things you cant change.

 

Marlayna J 2

06/28/2011 07:55:14

1.) I can tell the the relationship between the effort arm and the resistance arm depended on the position of the fulcrum. And depending on that is how much wait would go on either side.

2.)You can do multiple tests on the same experiment and change the different variables that are effecting the experiment.

3.)No, because if you mess up on something there might not always be a chance to fix that error.

 

Tyra W.

06/28/2011 07:55:28

I think by making a generalized model would be to use the ruler as a balance by placing it excalty in the middle and measuring objects

 

Tirae' A.

06/28/2011 07:55:50

1.) The relationship between the effort arm and the resistance arm of the lever is that they have to have the same amount of washers on each end if the fulcrum is centered.

2.) We can develop a generalized model for solving a problem by doing trial and error over and over and over again until we find a generalized model.

3.) They'd be affected negatively
because you can't try things in the real world because lives are at risk and that is not anything that should be taken lightly.

 

Kenneth C

06/28/2011 07:56:10

1. In my experiment i saw how LE and LR is different because it shows whats different from what and how whats bigger and more than the other.

2. You can make mulipile test on one experiment which you do the equations or question in many ways.

3. I think you can use different ways in experiences in your real life and how deal with different conflicts are different situations.

 

Josh S.

06/28/2011 07:56:36

1.) It varied because of where the fulcrum was on the pencil.How high or low or how much effort.
2.) I don't think there is a model just the trial and error is the best.
3.) Trial and error can be applied in life situations as well as classroom situations.

 

Kaylah S - 2

06/28/2011 07:56:42

1. The effort arm and resistance arm of my lever depended on where i put the fulcrum. The effort arm would have more washers on it do balance off the resistance arm.
2.We can develop amore generalized model for solving a problem by drawing it out.
3.Trial and error strategies can be affected by real world considerations because using the trial and error meathod you will get many different results and will be able to know which way to solve your problem

 

Breion P.

06/28/2011 07:56:57

1. It took time to get one side to have more mass than the other but eventually we got it.

2. We would have to do an observation first then we can have a model to look for.

3. It can harm other people just by makin one little error that's why we always do practice test.

 

JadaM2

06/28/2011 07:57:27

1) I can tell you the diffrence between them , because the effort did more than the resistance .


2)If we would have continue to work with the washers then we could have figurerd out a way to make them balance.

3)The trial and error will effect the real world because , it would be so many diffrent ways and it will also give u diffrent results.

 

Tamyra F.2

06/28/2011 07:59:17

1.The effort of E arm and R arm is depending on what all you measured.
2.

 

Jasmine Samuel

06/28/2011 07:59:42

1.)Te relationship between was based off were the fulcrum was placed.
2.)You can develop a generalized model by doing multiple trials.

 

Chad M

06/28/2011 08:42:17

I figured out that the side with less rings and inches was higher on the folcrum.

 

Ariel D-R 3

06/28/2011 08:45:45

1. The relationship between the Effort and Resistance Arm are that they both depend on the Fulcrum.
2. We can continue trial and error until we come up with the best model.
3.Real world considerations affect Trial and Error because it can give you many different results.

 

Khial J 3

06/28/2011 08:46:41

the more the measurement increased on the resistant side of the lever, the more weight is needed to balance or shift in the opposite direction.

 

Kyra S 1

06/28/2011 08:46:44

1. i can tell that the effort arm and the resistance arm varies depending on where the fulcrum is located.

2. you might develop a generalized model for solving a problem by trying different ways in order to get to the right solution.

3.trial and error strategies are affected by real world considerations because once you move one situation to another one end beocmes heavier and the other lighter.

 

Symone Palmer

06/28/2011 08:46:54

1. The relationship between the Effort arm and the Resistance arm of your levers depends on the positioning of the fulcrum. When the fulcrum is closer to the effort arm, it becomes harder to raise the resistance arm, and vice versa.

2. Depending on the distance of the fulcrum to another, the number of washers required to raise the opposite side will increase as long as the distance of the fulcrum to the other side decreases.
3. In the real world, one must conduct trial and error tests in almost everything they do in order to accomplish a task. If one is not given specific instructions, one must try and fail until they come up with a solution.

 

Nikiah C. 3

06/28/2011 08:47:31

1. During the experiment I noticed that as the effort arms got shorter, they needed more weight to try and balance the arms out.

2. To develop a generalized model for solving a problem you might do trial runs to gather data and kind of assess what a solution can be.

3. Sometimes in real life situations, you may not be able to do trial and error situations for the safety of the public or yourself.

 

Alexis P.3

06/28/2011 08:47:40

1. The effort arm and the resistance arm depends on the fulcrum.
2. By creating a first class lever.

 

Tyler W. 3

06/28/2011 08:47:50

1. the ea is realated to the ra because they both rely on the position of the fulcrum.
2. you may be able to solve it by trying different positions and trying different trials to find the exact data.
3. they might effect it because we were just randomly picking numbers and nothing was set and we could have used more advanced tools to get better answers.

 

Khial J 3

06/28/2011 08:48:12

Possibly using a table to organize your work and data or any other graphic organizer able for use.

 

AubreyL3

06/28/2011 08:48:21

We could tell that when we put the different weights on the lever it changed.

We can even the weights, which makes the lever even.

If we build the levers equally then we wont have problems in the environment

 

Danielle S. 3

06/28/2011 08:49:24

1. Based on my data the EA and the RA are related because they both rely on the position of the fulcrum.

2. You can develop a generalized model by testing different situations until you get accurate data.

3. Trial and Error might be affected by real world considerations because it could give you different ways to solve different problems.

 

Khial J 3

06/28/2011 08:50:13

based in real life situations, using a lever scale could relate to these types of situations

 

Kc

06/28/2011 08:51:35

1) TH effort arm and the resistance arm is depending on what all that is measured in the data.
2)If we continued to test the washers we could have figurd out a way to ballance them.
3)Thr will be complictaions but they can hlp you have different methods

 

Asiyah

06/28/2011 08:53:30

1) The relationship between them is very similar when the fulcrum is involved. Both the effort and the resistance is effected ehrn the fulcrum is moved.

2) I dont really know.

 

Therrance

06/28/2011 08:56:09

1.The relaionship between the Effort arm and Resistanc arm is that they complete each other. They must equal and what you have measured. The class lever is also based on the fulcrum.

2.We develop a generalized model for solving a problem by doing mutiple trails and different experiments with the washers.Make equations and problems.

3.Trial and error strategies can be affected by real world considerations by helping with practice test. There are more varibles, you need like a rough draft then you make your final.

 

'Bri Anna / o3

06/28/2011 08:56:20

1. Which ever side the fulcrum is closer to youu had to have more washers

2. A real fulcrum & real tools

3. There are many ways you could have done the project & one error could mess it up

 

K'yana Johnson

06/28/2011 08:58:38

1. The Effort and the Resistance arms relationship was depending on where I put the fulcum to balance the ruler to make each side equaL.

2.We can use real materials.

3. Trial and Error might be affected because of different conclusions.

Cambryce B. 4

06/28/2011 09:44:41

1. What can you tell me about the relationship between the Effort arm and the Resistance arm of your levers? Be detailed.
We needed more resistance than effort most of the time depending on where the fulcrum was.

2. How might we develop a generalized model for solving a problem?
Use different material posibly bigger.

3. How might trial and error strategies be affected by real world considerations?
Depending on the trail there are a possible number of errors.

 

Mahlik H. 4

06/28/2011 09:45:02

1. Both arms have some similar ways.
If one side is six and the other is six, its even. But, it won't stay far away from being even.
2. See if the numbers for E & R are similar.
3. How bridges and, overpasses are built.

 

Aree V4

06/28/2011 09:45:51

1. The relationship depended on where i placed my washers on the ruler.

2. Use real materials.

1. What can you tell me about the relationship between the Effort arm and the Resistance arm of your levers? Be detailed.
It depended on where i put the fulcum to balance the ruler and make each side equal.
2. How might we develop a generalized model for solving a problem?
We can continue trial and error until we find a solution model.
3. How might trial and error strategies be affected by real world considerations?
It can affect you because you are not really getting exact answers ! :)

1.If the fulcrum is in the middle of the ruler, it takes the same amount of washers to balance it out. If the ruler is close to the end, it takes more washers on the other side.
2.You might be able to make a generalized model for problem by testing it out a couple of times & recording til you get it.
3.People change the fulcrum to make a difference in the balance.

1.The effort side is constantly being applied weight while resistance maintains its status when you start the experiment.

2.Test this experiment in different scenarios.

3.They are all effected but differently.

1.The effort arm is the arm that is trying to lift the resistance. The more length a rsistance lever has can make the effort level require mre force to lift it.
2.real tools and cause and effect
3.They can reflect on how the real world may happen an how it will happen if you do it liike the trial.

1. The side of the lever that had the most inches , was the side that was like the heaviest almost each and every time we tried to balance the washers .

2. We might develope a generalized model by using real materials , such as a real balanced scale , and real wieghts and not washers even though they do contain weight.

3. Trial and error strategies may be affected by real world consideration by many different ways . There are many problems and obstacles you may have , depending on the scenario that you are dealing with .

1. The relationship between the effort arm and the resistance arms is the arms weight will depend on where the fulcrum.

2. We might develop a generalized model to solve the problem by creating a simple machine that balances objects.

3.You could always trail an error to see if the results will change. Multiple test are always good to see if something is consistent.

1. I concluded that the side with the more inches needed less washers.

2. You might e able to developa generalized model for solving a problem by running many trials.

3.Trial and Error will help you develop and gather many thoughts in this world for a conclusion.

1. The side of the ruler, that had the most inches end up being the most heaviest side.

2. We can come up with different trials, and we can use more materials.

3. There are so many different scenarios, which can cause the experiment to have many errors.

1. What can you tell me about the relationship between the Effort arm and the Resistance arm of your levers? Be detailed.
Effort arm and resistance arm must complete it self, it equals up to the same amount.

2. How might we develop a generalized model for solving a problem?
We can develope a generalized model by doing different experiments with the washers.

3. How might trial and error strategies be affected by real world considerations?
Trail and error strategies be affected by real world consideration by doing practice questions and skills.

1.)The relationship between EA and RA is that when one side is when one is longer it needs less washers than the shorter with more washers
2.)Trying different problems with diffrent materials.
3.)There are many trial and error situatuons already with conflicts in the world.

1)the longer the length of the resistance the more washers are needed on the other side with the effort side
2)To develop a genralized model for a problem you can run trials and experiments to see what happens in different cases and scenarios
3)You may not always be able to use this strategy because some times you only get one shot and you dont have room for error.

1. What can you tell me about the relationship between the Effort arm and the Resistance arm of your levers? Be detailed. I can tell you that the relationship between the Effort arm and the Resistance arm of your levers are the fulcrums.

2. When we developed a generalized model for solving problem we had many errors and we had to re do them to get an accurate answer.

3. Trial and error sttategies are not always the way in the real world because it could mess up your conculsion.

1. The relationship between the Effort arm and Resistance arm is that the shorter the effort arm, the longer the resistance arm.

2. By testing more than one trials. The fulcrum is basically the base for the other objects. Without the fulcrum, the model wouldn't succeed.

3. Sometimes in life, you can't have many chances at doing things. In society now, it's either you get the topic or not.

 

Diamond D. 4

1.) The resistance arm and the effort arm never seemed to balance out on the fulcrum, not only that but even an equal amount with my results made the inches differ. They were never 6 and 6, or never could the washers be the same. The effort arm seemed to hold more washers than the resistance arm of course.

2.) All the materials are already simple enough or generalized.

3.) This trial and error can be useful especially when it comes to architecture. For instance settling a foundation of a huge corporate building on one support beam!

 

Kolby Owens

06/28/2011 09:52:07

1.) I have noticed that there were always more washers on the effort side of our lever. There were only 2/6 exceptions to this rule we found.

2.) We can test and perform different tests and observations.

3.) In real-life situations when you have a problem, you do have to do trial and error. The only way to solve a problem is to try and sometimes you're going to fail. But you have to try again. Thats trial and error in the real world.

1.the effort and the resistance arms relationship is depending on the balance of the ruler and were i set it.

2.we can use real materials.

3.trial and error is affected because of the different posible conclusions.

 

Taylor R 4

06/28/2011 09:52:19

1. The farther appart they were the more washers you had to add to each end, which showed the resistance on the resistace arm.

2 i dont know how to answer this question

3. Trial and Error can be used in almost every situation because not everything will go as planned and you might have to re-evaluate what you have and start over fresh to get a different outcome than before.

 

Gabrielle L (4)

06/28/2011 09:52:32

1)The relationship between the effort and the resitance levers are one in the same. If the folcrum is closer to one end then then the opposite end had to be a lot heavier then when it was in th middle.
2) You can use many different objects to do display balances
3) In the real world we will use trial and error because we will not know exactly what will happen when we try something new.

 

JerrionaD4

06/28/2011 09:57:40

1.)The longer the length of the resistance the more washes we need one side.
2.)You can run trails and experiments to see what's your outcomes.
3.)It affects the real world beacuse you only get a certain amount of times to mess up, but there are different ways to do the trails.

1.
It didnt matter how many washers were on either side . What made the lever change sides was determined based on where the fulcrum was .

2.
Do trial and error experiments until you get that data that you want to get .

3.
They may be effected because you might not never find the solution . Or someone else might always have different conclusions than you do .

This was a very interesting project. It took up a lot of my attenttion.

 

Trayona Belford

What I noticed from this experiment is that moving the fulcrum it caused the change in in the lever goes up or down. Also, that the washers made a big difference when u put more on one end it either bring the lever up or down.

 

veli

1. everytime the fulcrum is moved the resistance and effort both change.

2. doing different trials

3.

 

nicholas

1.)I can tell that the effort arm and the resistance are of the levers varied depending on where the fulcrum was. Either the effort arm or the resistance arm required more weights.

2.)You might be able to develope a generalized model for solving a problem by testing out different scenarios.

3.)They might be effected by there being so many different scenarios to account for in a trial and error strategy applied to real considerations.

 

jacob lindsay

09/20/2011 06:30:45

1. tthe effort and resistance forces may vary on the arms but what really matters is the place of the fulcrum.

2. The way you can make a generalized model with the class is to replicate the experiment or something.

3. well i guess it helps by like helpin to show some sort of a simulation or something.

 

Shamica G

09/20/2011 06:30:52

This project was very fun and different it made you think of many different have of how to have your washers . It was funny to me because I figure different ways of making 6 different examples.

 

Jeffrey

09/20/2011 06:34:44

1.1.the longer the effort arm, the more weight is required on the resistance arm to either balnce it out or overcome
2. You can use many different objects to do display balances
3. .)This might be affected by the real world because situation like kids playin on a see saw relates to this experiment.

 

terron

09/20/2011 06:34:59

1. The relationship between the effort arm and the resistance arms is the arms weight will depend on where the fulcrum.

2. dont know to approach this question

3 Multiple test are always good to see if something is consistent.

 

Na'Sha Burton

09/20/2011 06:36:44

1}What I can tell you about the relationship between the effort and the resistance level is that if the fulcrum is close to lets say the effort level side then that would be the side that gose up no matter how many washers you put on there and it gose for the resistance side to.

2}You can do differnet runs of tests with real tools to get until you get the results you want or that you know are right.

3}It might be affected because having trial and error strategies cant really get what your looking for and it might take you on the wrong past.

 

John and Busby

09/20/2011 06:37:05

1)Effort and resistance will vary depending on the positon of the vulcrum ,and the amount of weight on each side. If there is more weight on the resistance, and the fulcrum is closest to it, the resistance side will drop.

2)You can develop this by performing experiments and many different scenarios.

3)Through trial and error ytou can develop conclusions, and troubleshooting for all problems. You can also figure out what will happen when you perform different functions.

1. Both of the arms work against each other and with gravity. Depending on the weight will result on the total resultant resistance.
2. Test the lever when both of them being balanced and observe the weight change as we add to it.
3. It m may not be accurately balanced or placed in the right position.

2. A way you can generalize a model is by replicating the experiment.

3. By showing a simulation

 

Larreon

The fulcrum is an very interesting piece of technology that depends on the weight which can shift the washers weight

1 the relationship of effort and resistance in our experiments was that the majority of the time the effort surpassed the resistance but effort was at it's greatest when the fulcrum was closest to the ends.
2 by creating a drawing of the lever at it's most efficient.
3Trial and error would be effective because we would figure out waht works best for a specific situation or most situations that apply to the reall world.
