Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent).
Efficiency = Useful Work Output ÷ Work Input

∙ 14y agoAs energy cant be converted without loosing some portion of it (thermodynamics), comparison between output and input work is used. When no energy is lost it is said to be efficient. In summary the input energy should be equal to the output energy/ work done.

What is a comparison of a machine's output work toit's?
the comparison of a machine's output work toit's
Is the comparison between output and input work ideal mechanical advantage?
No. That ratio is 'efficiency'.
What is a comparison of a machines work output with the works input?
The ratio between the two is called the efficiency.
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
What is a comparison of a machines work output and work input?
mechanical efficiency
What is a comparison of a machines work input and work output?
mechanical efficiency
What is a comparison of a machine's work input and work output force?
Mechanical efficiency
Difference between force output and Work Output?
force output x distance = work output ~same for input
Why the output work is always less than the imput work in a real machine?
There are always losses in the system . Friction causing heat. Vibration taking away energy . There are no prefect systems therefore there will always be losses.
Differences between input work and output work?
Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine.
What is the differences between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
What is the difference between work input and work output?
Work Output is the work done BY a machine. Work Input is the work done ON a machine.
