Explain why the mechanical advantage of the class III lever is always less than 1.

Solutions:

The effort E is located between the fulcrum F and the load L in a Class III lever. As a result, the load arm is always smaller than the effort arm. Therefore, M.A. is always less than 1 of Class III lever.
