In that case, the efficiency is said to be 1 - or equivalently, 100%.
Output APEX
Input??
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.
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.
