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.

Can you make work output of a machine greater then the work input?

No. And you cannot make it greater THAN the input, either.

What prevents the output work from never being greater than the input work?

That would be resistance. Oftentimes referred to as friction.


What is the difference between mechanical advantage and Efficiency?

A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force. This is compensated for by the fact that the distance moved by the input is greater than the output so that in an ideal machine, the work input (Force*Distance) is the same as the work output. In real life, though, you always lose some energy - in the form of frictional heat, or sound.A negative mechanical advantage is the opposite. A small distance moved by the input is converted to a large distance moved by the output. But the force in the output is correspondingly reduced.A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force.

Why is the output work always less than the input work for a real machine?

because output work is input work divided by two

Why it is impossible to have output greater than work input?

Whenever we do any work some energy will be converted into any form other than the actual input energy for the work to be done so it is impossible to have the output greater than work input example : some energy will be converted to heat energy due to friction

Why the output work for any machine cant be greater than the output explain?

-- The output work can't be greater than the output because they are, by definition of the terms, the self-same quantity, and consequently can be neither greater not lesser, but must at all times remain identical. -- The output work can't be greater than the INPUT ... unless additional energy is supplied inside the machine ... because total energy of a system is conserved, and cannot be created ex nihilo.


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.
