Mechanical Efficiency

Mechanical efficiency measures how effectively a machine converts input energy into useful work. It is calculated by dividing the useful output work by the total energy input, then multiplying by 100 to get a percentage. For example, if a machine uses 100 units of energy but only performs 80 units of useful work, its efficiency is 80%. High efficiency indicates minimal energy loss, often as heat or friction. Mechanical efficiency helps assess the performance of machinery, guiding improvements to reduce energy waste and optimize operation.
