Mechanical Advantage

Force amplification of a simple machine.

Formula

MA=FoutFinMA = \frac{F_{out}}{F_{in}}

Variables

F_{out}Output force
F_{in}Input force

Example

A lever giving 200 N out for 50 N in has MA = 200/50 = 4.

Did You Know?

Give Archimedes a lever and a place to stand, he said, and he could move the Earth.
