Question

What is the principal of an ideal meachine

Answer 1

Ideal machines have the theoretical maximum performance, and therefore are used as a baseline for evaluating the performance of real machine systems. A simplemachine, 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.

Answer 2

The principal of an ideal machine is it can perform smoothly without more noise and sound and it uses very less amount of energy.
It has more power than any other machine.
