Explanation:
Most simple machines provide a mechanical advantage greater than 1 (MA > 1) so that work is made easier; i.e., the input force is increased, and therefore, the mechanical advantage is less than the output force.

Answer:
In order to make use of non-collapsed mechanical advantage, it is necessary to use a 'true length' rotary lever. ... If the distance from the fulcrum to the input force is less than from the fulcrum to the output force, then the lever reduces the input force.
