Mechanical Advantage of a Screw Using Lead

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

The mechanical advantage of a screw is \[Pi] times the diameter of the screw divided by the lead of the screw thread.

Formula

QuantityVariable["MA", "Unitless"] == (Pi*QuantityVariable["d", "Length"])/QuantityVariable["l", "Length"]

symbol description physical quantity
MA mechanical advantage "Unitless"
d diameter of screw "Length"
l lead of screw thread "Length"
