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.

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 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.
What is the reason a machine's output work is always less than the input force?
Entropy.
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 is the output work in a machine always less than the input work?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
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%

In a real machine the work output is always less than the work input.?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
Why is work output by a machine always less than the work input?
It is usually unavoidable that some energy is wasted.
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.
