Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. Machine components designed to man...

(force ratio) The ratio of the output force (load) of a machine to the input force (effort). In the case of an ideal (frictionless and weightless) machine, mechanical advantage = velocity ratio.

A mechanical method of increasing an applied force. Disregarding the effects of friction, if a force of 100 pounds applied to a tackle is magnified to a force of 400 pounds, the purchase or mechanical advantage is said to be four to one, or 4: 1.

In physics, the ratio by which the load moved by a machine is greater than the effort applied to that machine. In equation terms: MA = load/effort. The exact value of a working machine's MA is always less than its theoretical value because there will always be some frictional resistan...
