Work output can never be more than work input. That's a law of nature.
In the real world, it's always less.

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 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%.
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.

Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
Work output can never be greater than?
Work input.
When a machince is used to perform a task work output is always what than work input?
Work output is always less than work input. This is related to the Law of Conservation of Energy.
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.
Is it true that when a machine is used to perform a task work output is always more than work input?
No, it is not true.
Why is always work output less than work input?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.

What is the definition of output and input work?
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
Why is a machines output work always less than its input work?
Because it is
