When the IMA is compared to AMA in the real world

the value of the ideal mechanical advantage (IMA) is always larger than the actual mechanical advantage (AMA).

Explanation:

A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.

Basically, a simple machine allows for the transformation of energy into work. The six simple machines are; lever, wedge, inclined plane, screw, wheel and axle, and pulley.

Efficiency can be defined as the ratio of actual mechanical advantage (AMA) to ideal mechanical advantage (IMA) or the ratio of work output to work input of a machine.

Mathematically, the efficiency of a machine is given by the formula;

When the ideal mechanical advantage (IMA) is compared to actual mechanical advantage (AMA) in the real world, the value of the ideal mechanical advantage (IMA) is always larger than the actual mechanical advantage (AMA) because some of the effort are used to overcome frictional force and the efficiency of all machines is usually less than one (1).

This ultimately implies that, no machine designed and developed by humans is one hundred (100) percent efficient.
