Question: At which marked point of a lever should less force be applied if the object needs to be lifted?


Solution:
The farther the force is applied from the fulcrum, the less force needs to be applied for an object of the same weight.

In case A, the distance from the fulcrum to the point of force application is greater, so less force needs to be applied.

In case B, the distance from the fulcrum to the point of force application is smaller, so more force needs to be applied.
