Mini-Quiz: Relationships in Levers

by Ron Kurtus (22 June 2016)

Take this Mini-Quiz to check your understanding of the lesson material.



1. How is the distance that the output load moves related to the angle of the lever?

It is the inverse of the angle

It is proportional to the angle

It depends on the speed

2. Can the output speed ever be the same as the input speed?

Yes, if the fulcrum is in the center of the lever

It is uncertain, since no one has ever tried it

No, because then the Law of Conservation would not hold

3. How does the force relationship to the lever arms compare with the speed relationship?

They are exactly the same

It depends on the load

It is the reciprocal of the speed relationship

If you got all three correct, you are on your way to becoming a Champion in Understanding Machines. If you had problems, you had better look over the material again.
