It's efficiency would be 100%, but it's basically a theoretical ideal, because no matter how much it is minimized, "machine" automatically means a certain amount of friction, and a certain amount of heat generated, even if they are tiny amounts. That prevents 100% efficiency.

How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
What the measure of the ratio of useful work output to work input?
Efficiency
The ratio of useful work output to work input is a measure of?
Efficiency
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
If the input work on a machine is equal to its output work does the machine has efficiency?
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.

How much work put into a machine is changed to useful work put out by the machine?
90%
Why does a high-efficiency machine is more desirable than low-efficiency machine?
High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.High efficiency means that a large percentage of the energy used is converted to something useful (the desired output of the machine), and a low percentage is wasted.
The ratio of useful work output to work input is a measure of?
Efficiency
What is the formula for efficiency of a machine?
useful energy output divided by total energy output x 100 give answer as a percentage, which is why you multiplied by 100
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
What is the measure of how much useful work a machine puts out compared to the amount of work put into it?
That is called the efficiency, and it is a number between 0 and 1 (or 0% and 100%). It is obtained by dividing output power / input power.
What is efficiency and how is it calculated?
The efficiency is output divided by input.
If the input work on a machine is equal to its output work does the machine has efficiency?
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%.
