100 % effeciency ... in the real world found only in electric heaters.
................................. [note - all loses are heat]
The machine would be one with 100% efficiency. None of those are available.
If the useful energy output of a system is equal to the energy input, the following calculation can be done:Efficiency = (Useful energy out) / (Energy In)Efficiency = 1Efficiency = 100%Therefore, the machine you describe does have an efficiency value, which is equal to 100%. Very few situations like this exist though, unfortunately.
Yes.
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.

If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
The output of a machine depends on the manufacturer's testing variables. Horse power output is usually roughly equal to one horsepower.
In theory, work output might be equal to work input; that would be 100% efficiency. In practice, the output of a machine will be less than the input; i.e., some energy will be lost.In theory, work output might be equal to work input; that would be 100% efficiency.

It is usually less. The reason for this is that some energy is usually lost (wasted) in the machine.
For a motor's output power to equal its input power, the motor's efficiency must be 100%. As no machine, particularly a rotating machine, can possibly achieve 100% efficiency, there is no condition under which its output power can ever match its input power.
