Mechanical Advantage

Mechanical Advantage (MAMA) is the amplification of force by a mechanical device and expressed as the ratio of output force (FoF_o) over input force (FiF_i), or MA=Fo/FiMA=F_o/F_i. A simple example of mechanical advantage is Archimedes's famous lever quote: "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world."

A mechanical advantage less than one will increase the output speed, whereas a mechanical advantage greater than one will increase the force.
