That is called the machine's efficiency. It is a number between 0 and 1 (or between 0% and 100%).

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.
The ratio of output work to input work is?
efficiency
What is output work divided by output force?
Output distance is.
Work output can never be greater than?
Work input.
What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.
Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
The work output of a machine divided by the work input is the?
efficiency.
How do you find the mechanical efficiency of a pulley?
you have to do: work (output) divided by work (input) = F x d (output) divided by F x d (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.

What is defined as input work divided by output work?
-3/-45
What is the definition of mechanical efficiency?
Output work divided by input work
If a machine's input work and output work are equal it has a high what?
efficiency
What is the work output of machine divided by the work input called?
That is called the 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.
Why is the work output of a machin never equal to the work input?
Some work input is used to overcome friction.
In order for work output to equal work input there must be?
Equalling for work input - now that's a fine idea
Is work output greater than work input?
No. Work output is less than or equal to work input. Since some energy (work) is lost in most processes, it will usually be less.
