The term ideal machine refers to a hypothetical mechanical system in which energy and power are not lost or dissipated through friction, deformation, wear, or other inefficiencies. 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. In this case, the mechanical efficiency is 100%.Mechanical efficiency is the performance of the machine compared to its theoretical maximum as performed by an ideal machine. The mechanical efficiency of a simple machine is calculated by dividing the actual power output by the ideal power output. This is usually expressed as a percentage.

Explanation:
An ideal machine is a hypothetical device that follows the principles of physics and mechanics to perform work. The concept of an ideal machine is used to explain how machines work and to calculate the amount of work done. The following points explain why the amount of energy put into an ideal machine must be equal to the output energy:
Law of Conservation of Energy: The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed, only transformed from one form to another. This means that the total amount of energy in a closed system remains constant. In the case of an ideal machine, the input energy is transformed into output energy, but the total amount of energy remains the same.
Efficiency: The efficiency of a machine is the ratio of output energy to input energy. In an ideal machine, the efficiency is 100%, which means that all the input energy is converted into output energy. If the input energy is greater than the output energy, the efficiency is less than 100%. If the input energy is less than the output energy, the efficiency is greater than 100%. However, an ideal machine cannot have an efficiency greater than 100%, as it would violate the law of conservation of energy.
Perpetual Motion: Perpetual motion is the concept of a machine that can operate indefinitely without an external energy source. This violates the law of conservation of energy, as it suggests that energy can be created out of nothing. An ideal machine cannot be a perpetual motion machine, as it must obey the laws of physics and mechanics.
Therefore, it can be concluded that the amount of energy put into an ideal machine must be equal to the output energy, as it follows the laws of physics and mechanics and satisfies the law of conservation of energy.
