Question

state the principle of an ideal machine.​

Answer 1

Explanation:

An ideal machine is that in which there is no dissipation of energy in any manner. The work output is equal to the work output i.e., 100 % efficiency.

Answer 2

We know that energy can neither be created nor be destroyed. But there is always a possibility of conversion of energy from one form to another.

When an undesired conversion of energy happens in a machine, it is called energy dissipation.

Every practical machine dissipates some amount of energy.

The concept of an ideal machine is just hypothetical, i.e. a machine in which there is no dissipation of energy. In other words whatever we input we get as output, i.e. the efficiency is 100%.
