When you input force to do work, the output work cannot be greater than what is
put in, because work is energy, and energy is 'conserved'. That means it can't be
created out of nothing.
If you had a box that could put out more work than you put in, you would be king
of the world. Once you get the box going, you could take off enough of the output
work to put back into the input and keep it going, and you'd have some left over
that could be used to generate electricity, run a car, lift a load, cut wood, cook a
fish, heat a room, power a boat, weave a rug, boil water, plow a field, etc. And
your box could do any of these things without a single drop of oil or lump of coal!
It's called "perpetual motion". It's fundamentally impossible, but scam artists for
hundreds of years have been able to shake millions of dollars out of investors who
could be convinced that you can get more work out of a machine than you put it.
YOU CAN'T MAKE THE WORK OUT PUT GREATER THAN THE INPUT BECAUSE FRICTIONS ALWAYS PRESENT SO YOU WILL NEVER HAVE 100% EFFECIENCY
All machines are limited by the Laws of Thermodynamics.
The Carnot cycle shows the maximum efficiency of any process for a given temperature. Efficiency, (work output:work input), is inevitably reduced by the presence of flaws in operation and or design of the machine. Natural inefficiency factors also play a great part in this reduction: friction, air drag, rusting, etc. There has yet to be a 100% efficient machine
That's easy to answer with the law of Conservation of Energy ... energy is never
created or destroyed, it just gets moved around, a lot like snow in northern Alaska.
Put some energy into a machine, and that's the only energy that's available to come out
the other end, unless somebody pours in some more energy in the middle. Energy can
never just magically appear out of nothingness somewhere inside the machine.
The output work is less because of what is lost to heat and friction within the machine.
The output work is always slightly less than the work input work. This is because some of the work done is used to overcome friction created by the use of the machine. However the work is not lost. The output work plus the work done to overcome friction = the input work. The less work the machine does to overcome friction the greater the efficiency.
No, the output distance is not always greater than the input distance. It depends on the specific situation and factors involved.
The output work from a machine cannot be greater than the input work because of the law of conservation of energy. Energy cannot be created or destroyed, only transformed from one form to another. Therefore, the output work of a machine cannot exceed the input work that was initially put into it.
This is possible when using a lever system with the rake, where the input force is applied over a shorter distance but results in a greater output force over a longer distance. The mechanical advantage gained from the lever system allows for the output force to be greater than the input force in this scenario.
In an ideal machine, if you exert an input force over a greater distance than the output force, the input force will be smaller than the output force. This is because work input is equal to work output in an ideal machine, and work is calculated as force times distance. Therefore, if the input force acts over a greater distance, the output force must be larger to balance the work done.
No. And you cannot make it greater THAN the input, either.

The Output Force Will Most Likely Be Greater Than The Input Force. So "OUTPUT" Is Greater Than "INPUT".
Output is always greater than input. The output is multiplied from input.
No, the output distance is not always greater than the input distance. It depends on the specific situation and factors involved.
Work input.
No.

In general, no – energy input is not usually greater than energy output. In a closed system, energy is conserved, meaning that the total amount of energy remains constant. However, in real-world systems, there may be inefficiencies or losses that result in some energy input being converted into forms that are not useful as output.
-- 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.
No. And you cannot make it greater THAN the input, either.
