That is called the machine's efficiency. It is a number between 0 and 1 (or between 0% and 100%).

The work output of a machine divided by the work input is the?

efficiency.


How do you find the mechanical efficiency of a pulley?

you have to do: work (output) divided by work (input) = F x d (output) divided by F x d (input)


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.

What is the definition of mechanical efficiency?

Output work divided by input work

-3/-45


What is the work output of machine divided by the work input called?

That is called the efficiency.


If a machine's input work and output work are equal it has a high what?

efficiency


Why is the work output of a machin never equal to the work input?

Some work input is used to overcome friction.


How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?

If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.


If the input work on a machine is equal to its output work the machine has effciency?

If the input work equals the output work, the machine has 100% efficiency, meaning it is able to convert all the input work into useful output work without any losses. An efficient machine is desirable as it maximizes the output for a given input.


In order for work output to equal work input there must be?

Equalling for work input - now that's a fine idea


What means work output divided by work input?

Work output divided by work input is known as the efficiency of a system. It represents the ratio of useful work output compared to the total work input required to perform a task. A system with high efficiency is able to convert a larger portion of input energy into useful output energy.
