mechanical advantage

Force-amplifying effectiveness of a simple machine (lever, wedge, wheel and axle, pulley, or screw). The theoretical mechanical advantage of a system is the ratio of the force that performs the useful work to the force applied, assuming there is no friction in the system. In practice, the actual mechanical advantage will be less than the theoretical value by an amount determined by the amount of friction.


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
