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.


Why can efficiency never can be 100 percent?

The laws of thermodynamics imply that there will always be some loss of efficiency.


When efficiency is at 100 percent it is known as what with power factor?

"Unity"


What is the formula to calculate percent efficiency?

(work out/work in) x 100


Why a normal machine could not have the mechanical efficiency of 100?

Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.


What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?

The efficiency of the machine can be calculated by dividing the useful work output by the total input energy and multiplying by 100. In this case, the efficiency would be (35/100) * 100 = 35%.

What would a machine that had 100 percent mechanical efficiency be called?

A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.


How can convert efficiency to percent?

Work done = (force * distance)>Efficiency (%) = (Work done output / Work done input) * 100


What is the percent efficiency if a man expends 100 J of work and the work produced is 80 J?
