Q. Which distance is more important from the fulcrum for a lever

A
Distance of load to be lifted
B
Distance of the force applied
C
Distances of both load as well as of effort
D
None
Solution:

law of the lever, which was proven by Archimedes, It shows that if the distance a from the fulcrum to where the input force is applied (point A) is greater than the distance b from fulcrum to where the output force is applied (point B), then the lever amplifies the input force. On the other hand, if the distance a from the fulcrum to the input force is less than the distance b from the fulcrum to the output force, then the lever reduces the input force.
