Best Answer

All machines lose some of the input force applied to them as a result of friction and other forces. The efficiency of a machine refers to how much of the input work is converted to output work by the machine. You can find the efficiency of a machine by dividing the output work by the input work. Because the output work will always be smaller than input work, efficiency will always fall somewhere between 0 and 1, with 1 being a machine that has as much output as input work (not possible in the real world) and 0 being a machine that is totally useless because none of the input work is converted to output work.

Q: Equals the output work divided by the input work?

because output work is input work divided by two

Any machine that is 100% efficient. (None exist.)

Because the input work equals the output work

input force x input distance > output force x output distance -Novanet

the equation of mechanical advantage isFout (force, output)divided byFin (force input)the equation for Ideal mechanical advantage isDin (distance, input)divided byDout (distance, output)hope this helps a bit

Output work divided by input work

That is called the efficiency.

ANSWER: work input equals work output

In that case, the efficiency is said to be 1 - or equivalently, 100%.

Work output divided by Work input Times 100

Output is always greater than input. The output is multiplied from input.

Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
