<P> Mechanical advantage that is computed using the assumption that no power is lost through deflection , friction and wear of a machine is the maximum performance that can be achieved . For this reason , it is often called the ideal mechanical advantage ( IMA ) . In operation , deflection , friction and wear will reduce the mechanical advantage . The amount of this reduction from the ideal to the actual mechanical advantage ( AMA ) is defined by a factor called efficiency , a quantity which is determined by experimentation . </P>
