Want this question answered?
input
Efficiency = useful output power / input power
That is called the machine's efficiency.
the force you apply to a simple machine is force
please rephrase ur question so that it can be understood
In that case, the efficiency is said to be 1 - or equivalently, 100%.
The answer is mechanical advantage, not efficiency!
input
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.
Output(input), or O(i)
Efficiency = useful output power / input power
Efficiency = useful output power / input power
It is the efficiency of a machine.
so wut exactly is ur question?
That is called the machine's efficiency.
efficiency is a product of the input versus the output
the force you apply to a simple machine is force
