W o and w i can always be calculated as a force multiplied by a distance, although these quantities are not always as obvious as they are in the case of a lever. Due to the principle of conservation of energy, energy efficiency within a closed system can never exceed 100%. So far, no engine has ever gotten to 100%. That is why 100% efficiency in machines shall not be possible.

Why can a machine never be 100% efficient? Because power is the rate of energy utilization, efficiency can also be expressed as a power ratio. For an actual machine, the output work is always less than the input work, so the efficiency is always less than 1 because there is a loss of energy due to friction. Load lifted is always greater than the effort applied. Systems always tend toward a state of decreasing order unless more energy is provided into the system to counteract this tendency. The amount of work obtained from a machine is always less than the amount of work put into it. It follows the second law of entropy. All heat engine cycles must reject some heat for an efficiency of less than 100%. W o and w i can always be calculated as a force multiplied by a distance, although these quantities are not always as obvious as they are in the case of a lever. So far, no engine has ever gotten to 100%.
