Abstract
THE earliest statement concerning statical frictional forces between rigid bodies is usually attributed to Coulomb (about 1776). The principle of Coulombic friction is that the force (F) required to generate translation of one body relative to another is directly proportional to the external force (W) transmitted across the contact plane, so that: F = µ W (1) Where µ is the coefficient of (static) friction.
