the speed ratio of a machine can be calculated from its physical dimensions. the assumption of constant power thus allows use of the speed ratio to determine the maximum value for the mechanical advantage.









































section::::efficiency.:actual mechanical advantage.









































the "actual mechanical advantage" (ama) is the mechanical advantage determined by physical measurement of the input and output forces. actual mechanical advantage takes into account energy loss due to deflection, friction, and wear.









































the ama of a machine is calculated as the ratio of the measured force output to the measured force input,









































where the input and output forces are determined experimentally.
