It has 100% efficiency, and one might say that
the machine has replaced friction with fiction.

How input work and output work computed on each type of simple machines?
(Output work) + (friction losses) = (input work) on any type of machine.
The efficiency of a real machine?
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.
Why is the work output of a machine never equal the work input?
Because -a small percentage of the input is lost as heat from friction.
Equals the output work divided by the input work?
All machines lose some of the input force applied to them as a result of friction and other forces. The efficiency of a machine refers to how much of the input work is converted to output work by the machine. You can find the efficiency of a machine by dividing the output work by the input work. Because the output work will always be smaller than input work, efficiency will always fall somewhere between 0 and 1, with 1 being a machine that has as much output as input work (not possible in the real world) and 0 being a machine that is totally useless because none of the input work is converted to output work.
If the input work on a machine is equal to its output work the machine has efficiency?

A picture of a input and output machine in math?
if one answer is 6 and the other answer is 7, how do the output numbers from the input/output machines compare
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
What compares a machines work output with the work input?
That is called the machine's efficiency.
What compares a machines work output with work input?
That is called the machine's efficiency.
Im most simple machines the work output of a machine will overcome the what?
Work input.
What stronger work output or work input?
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.

If a machine's input work and output work are equal it has a high what?
efficiency
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
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.
How input work and output work computed on each type of simple machines?
(Output work) + (friction losses) = (input work) on any type of machine.
What is the difference between a ideal machine and real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
