If the work on a simple machine equals the output work, the machine is said to be 100% efficient

If the input work on a simple machine equals the output work, the machine is said to be 100% efficient

Explanation:

The machine is understood to be 100 per cent effective when the input work on a regular machine is equal to the machine work output. Since the performance formula is the ratio of output work to input work, and if it is 1, it is said that the system is 100 percent efficient, indicating that there is no loss. Their are following equations to understand the proportion of efficiency:

When output = input, efficiency = 100%

When output < input, efficiency < 100%

When output > input, efficiency > 100%.
