What causes the output work of a machine to e less than the input work?

Some of the input force is lost due to friction. If you are using a pulley system then there is friction between the rope and the pulley and there is also friction within the ball bearings of the pulley itself. If you are using an inclined plane there is friction between the plane and the object traveling upon it. In a friction-less world the input is equal to the output.

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.
What causes the output work of a machine to be less than the input force?
Some of input energy is wasted in heating up the molecules, sound,etc therefore the resultent output work is always less than the input force due to loss of energy.
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
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 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.
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).
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
How is the work output of a machine related to it's work input?
In an ideal universe, where there are no friction or heat transfer losses, work out = work in. In our universe, however, work output is always less than input. How much less depends on the efficiency of the machine's design.
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.
Why in a real machine the output work is always less the input work?
In a real machine, part of the energy (or power) is always wasted.
