In an ideal machine with no friction, energy efficiency is described as what percent?

Explanation:
In a frictionless, ideal machine, every bit of input energy becomes useful output work. Efficiency is defined as output work divided by input work, times 100%. Since there are no losses to friction, heat, or other inefficiencies, the output equals the input, giving 100%. The other percentages would imply some energy is lost somewhere, which doesn’t happen in an ideal, frictionless system.
