Question

what is ideal and actual mechanical advantage???

Answer 1

The Mechanical advantage is the ratio of force produced by the machine to the ratio of the force applied to it. It is used to figure out the performance of the machine

Answer 2

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 against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.
