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.
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.
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
What are the circumstances for which the output work would equal the input work in a machine?
The machine would be one with 100% efficiency. None of those are available.
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.
If a machine's input work and output work are equal it has a high what?
efficiency
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.

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 .
The output work of a machine compared to it input work is the of the machine?
Output(input), or O(i)
Is your power into motor equal to your power out of motor at no load?
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.
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
The ratio of output compaired to in input?
It is the efficiency of a machine.
If the output work of a simple machine equals the input work the machine is said to have efficiency.?
In that case, the efficiency is said to be 1 - or equivalently, 100%.
What is efficiency and how is it calculated?
The efficiency is output divided by input.
