WebActual mechanical advantage takes into consideration real world factors such as energy lost in friction. In this way, it differs from the ideal mechanical advantage, which, is a sort of 'theoretical limit' to the efficiency. The AMA of a machine is calculated with the following formula: AMA = R / Eactual. where. R is the resistance force, WebEfficiency in real machines will always be less than 100 percent because of work that is converted to unavailable heat by friction and air resistance. Wo and Wi 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.
