Question

What is principle of ideal machine

Answer 1

The main principle of an ideal machine is reduce human effort and make the work efficient, faster and easier.

Answer 2

Ideal machines have the theoretical maximum performance, and therefore are used as a baseline for evaluating the performance of real machine systems. A simple machine, such as a lever, pulley, or gear train, is "ideal" if the power input is equal to the power output of the device, which means there are no losses.
