What is the definition of a "first class lever"?


In physics, a first class lever is a type of lever in which the fulcrum is positioned between the load and the effort. In a first class lever, effort is applied on end, and load is at the opposite end. A good example of such a lever is a crowbar.

In a first class lever, force must be applied over a long distance for there to be a movement of the heavy load. The effort that is applied and the mechanical advantage depends on how far the fulcrum is from the load. The closer the fulcrum is to the load, the more the force applied and vice versa.

The first class lever is the one you may be most familiar with. It uses a fulcrum in between, and the applied force and load are at opposite ends. http://www.mca.k12.nf.ca/sm/lever/
