Mechanical Advantage of a Lever

Mechanical advantage is a measure of the force amplification achieved by using a tool, in this case a lever.

The mechanical advantage of a lever is the effort arm length divided by the load arm length.

Formula

QuantityVariable["MA", "Unitless"] == QuantityVariable[Subscript["d", "1"], "Distance"]/QuantityVariable[Subscript["d", "2"], "Distance"]

symbol description physical quantity
MA mechanical advantage "Unitless"
d1 effort arm "Distance"
d2 load arm "Distance"
