Mechanical Advantage of a Wheel and Axle

Mechanical advantage is a measure of the force amplification achieved by using a tool—in this case, a wheel and axle.

The mechanical advantage of a wheel and axle is the wheel radius divided by the axle radius.

Formula

QuantityVariable["MA", "Unitless"] == QuantityVariable[Subscript["r", "w"], "Length"]/QuantityVariable[Subscript["r", "a"], "Length"]

symbol description physical quantity
MA mechanical advantage "Unitless"
ra axle radius "Length"
rw wheel radius "Length"
