mechanical advantage

[mi′kan·ə·kəl əd′van·tij]
(mechanical engineering)
The ratio of the force produced by a machine such as a lever or pulley to the force applied to it. Also known as force ratio.

Mechanical advantage

Ratio of the force exerted by a machine (the output) to the force exerted on the machine, usually by an operator (the input). The term is useful in discussing a simple machine, where it becomes a figure of merit. It is not particularly useful, however, when applied to more complicated machines, where other considerations become more important than a simple ratio of forces. See Efficiency, Simple machine
