∙ 13y agoIt is the ratio of output power given by the machine to input power supplied to the machine.
i.e. Efficiency = output power of the machine / input power suplied to machine.

Why is a high efficiency machine is more desirable than a low efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
The efficiency of a machine is usually expressed in?
The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.
Describe why a high-efficiency machine is more desirable thana low-efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
What is the machine efficiency of a machine that produces 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
What is a machine with efficiency of less than one?
no machine has one
What is an efficiency ratio?
The efficiency ratio for a machine usually refers to the ratio of the useful energy available from a machine and the energy put into it.
How is a real machine and an ideal machine different?
An ideal machine can reach 100% efficiency as there is no friction or other restraints involved, whereas a real machine can never reach 100% efficiency.
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
What limits the efficiency of machine?
friction
Why were machine guns used?
Efficiency
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
