Class II Levers

In these types of levers, the fulcrum F and effort E are placed at the two end of the levers and the load L placed somewhere in between point of E and L. That is load(L) and effort(E) are at same side of the fulcrum(F) but it acts at the opposite direction.

In fig. AF is a class II leaver, F is fulcrum. In the point B and A. We apply the Load L and effort E respectively. Here BF is the load arm and AF is the effort arm. That is class II lever effort arm is always larger than load arm.

Therefore,

E × AF = L × BF

Mechanical advantage = W/P = AF/BF
