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.

The ratio of output compaired to in input?
It is the efficiency of a machine.
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
The ratio output power to input power in percent is called?
B. Efficiency
What is the efficiency is the output work is 12000 and the input work is 15000?
Efficiency as a percent is output/input * 100%12000/15000 * 100% = 80% efficiency which makes sense, because it takes more work (input) than it give out (output). So the efficiency should be less than 100%.
What is the Formula for calculating the efficiency of a machine?
Efficiency = Output value / Input valueFor example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
What of the machine compares the output work to the input work and is expressed as a percent?
That's the machine's "efficiency".
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
How does the output work compare to the input work for a machine that has an efficiency to less than 100 percent?
Then the output work is less than the input work. That description applies to every machine that has ever been built or will ever be built.
Why would a machine with 100 percent efficiency be considered an ideal machine?
No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.
What does efficiency compare energy output with?
With energy input
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
The output work of a machine compared to it input work is the of the machine?
Output(input), or O(i)
How is the efficiency of a machine calculated?
Efficiency = useful output power / input power
How is a machine's efficiency of a calculated?
Efficiency = useful output power / input power
The output work of a simple machine is than input work the machine is said to have less than 100 percent efficiency?
so wut exactly is ur question?
Compare the two stroke and four stroke engine in powe output and thermal efficiency?
compare the two stroke and four stroke engine in power output and thermal efficiency?
The ratio of output compaired to in input?
It is the efficiency of a machine.
