Leverage

What does this picture tell you about how we can use levers to gain a mechanical advantage? What is the relationship between the effort, the load and the fulcrum which allows the load to be lifted?

The picture shows that by using
leverage people can lift things that are many times our own weight.

By using levers you can do things you normally wouldn't be able to do. Like lifting things much bigger than our own weight.

This picture tells us that you could lift anything with a lever and the father away the effort is from the fulcrum the easier it is and the closer the load is to the fulcrum the less effert it takes.

Response Sheet-Levers
By:Sophie
I think Kevin was right because the closer the effort is to the fulcrom, the more effort is needed to lift the load. So Randy's lever needs more because the fulcrom is closer to the effort. Kevin's lever needs less effort because the fulcrom is farther away from the effort. So that is why I think Kevin's opinion was right.

I think that Kevin was right because the fulcrm is in a different position on Randy's lever than Kevin's, so it would probably take less effort on Kevin's than Randy's, becuse the closer the fulcrum is to the load, the less effort it takes. So Kevin,
YOU ARE CORRECT!

Kevin was correct since the position of the fulcrum is diffrent for both of their levers which would get you different results. Today and last week my class did an experiment in which we tested leverage. When we kept the load in the same place and moved the effort we found we found it most effective to put the effort as far away as possible from the fulcrum, when we kept the effort in the same place and moved the load we found it most effective to put the load closer to the fulcrum. Kevin's lever has the load closer to the fulcrum than Randy's. Also the effort is just as far from the fulcrum as Randy's. Bassically it would be more effective to use Kevin's lever.
