Answer:
Work done depends on the force applied and the perpendicular distance between the fulcrum and the point of action of force. Both force and perpendicular distance are directly proportional to the work done.

Answer:
work depends on:FORCE and DISPLACEMENT.
it is directly proportional to both of them.
work can be calculated by the product of force and displacement.
if displacement is in a certain direction to the applied force then work done is calculated by force*displacement cos(angle).
work done becomes 0when:-
*displacement is 0 or the initial point and final point are the same.
*displacement is in perpendicular direction to force applied.
