Although it is impossible for any machine to have an efficiency of 100%, it would in this case be 100%. Studies have shown that when ever there is motion, there has to be a loss of energy due to friction. So any rotating machine, big or small will have losses.
In that case, the efficiency is said to be 1 - or equivalently, 100%.
The answer is mechanical advantage, not efficiency!
input
so wut exactly is ur question?
please rephrase ur question so that it can be understood
Answer: Output force is the force exerted on an object by a simple machine.
Efficiency means to calculate that is the machine is efficient enough to save your bill or use less electricity. To calculate the formula is:Efficiency = Energy output (what is the machine producing) divided by Energy input (what is the machine taking or using).
Efficiency % = (work out / work in) * 100 (Work = force * distance)
Efficiency % = (work out / work in) * 100 (Work = force * distance)
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
output force divide by the input force is the mechanical advantage of a simple machine.The output force is the force that is exerted by the machine on an object, and the input force is the force that we exert on a machine.
