Question

Difference between ideal mechanical advantage and actual mechanical advantage

Answer 1

The actual mechanical advantage is less than 1 or greater than 1 whereas the ideal mechanical advantage is equal to 1.
In actual mechanical advantage there is a loss of effort but in ideal mechanical advantage, there is no loss of effort.

Answer 2

Mechanical advantage. Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces movement to obtain a desired amplification in theoutput force.

The actual mechanical advantage(AMA) is the mechanical advantagedetermined by physical measurement of the input and output forces. Actual mechanical advantage takes into account energy loss due to deflection, friction, and wear.
