Class 2 Lever

The figure shown here illustrates the key components of a Class 2 Lever. There is no change in the definitions of F1, F2, L1 and L2. Here are its main components:

F1: This is the force (effort) we apply at one end of the lever.

F2: The application of force F1 at one end of the lever results in a force (F2) being generated at the location where the weight (to be lifted) is located. This point is between the fulcrum and F1. The direction of F1 and F2 is identical. If the weight is less than F2, it will be lifted.

L1: This is the distance between the applied force and the fulcrum.

L2: This is the distance between the point where the weight acts and the fulcrum.
