The work you do on a machine is called work?
the work a machine does is the work output
what it takes to do the work is the work input
Computer is the electronic device which perform the logical and mathematical calculation.Computer is known as the versatile machine because it is very fast in every field and it the part of life without it we cannot imagine life. It can do the work faster and in Evey field the computer is use for making their work faster. It can perform the work fast so it is called versatile machine
Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful…
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.
