What is a machine in which work output is less than work input?

That means the efficiency is less than 100%. This is the case for any practical machine - some energy is always lost. Therefore, I don't think these machines have any special name.

Why is the work output of a machine always less than the work input?
In a real machine, the output work is always less because input energy will be converted to heat energy and lost.
Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
If the output force is less than the input force of a simple machine the mechanical advantage is less than one.?

Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes this it true, because a percent of the input energy is converted to heat, which causes the output to became less than the input.
Why is the work output of a machine always less than the work input?
In a real machine, the output work is always less because input energy will be converted to heat energy and lost.
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.

How does the output work compare to the input work for a machine that has an efficiency to less than 100 percent?
Then the output work is less than the input work. That description applies to every machine that has ever been built or will ever be built.
What is the reason a machine's output work is always less than the input force?
Entropy.
In a practical machine the power output is the power input?
In any practical machine, the power output is less than the power input. In other words, the efficiency of real machines is less than 1.smaller thanalways

Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
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.
Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes this it true, because a percent of the input energy is converted to heat, which causes the output to became less than the input.
Is the work output always less than the work input when a machine is used to perform a task?
yes
What is meant by efficiency of a machine?
It is the output energy compared to the input energy. This will always be less than 100%
