Question

No any simple machine has 100% of efficiency, why?

Answer 1

Answer:

Your question implies that there are simple machines that are 100% efficient. It cannot be true. No machine can be 100% efficient.

Explanation:

Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work). The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent.

Machine efficiency will always be less than 100%.
