coefficient of friction is a constant relation in agiven case, depending only upon the nature of the sur-faces in contact. This use of the term coefficient, to denote a constant factorwhose value depends upon the substance involved, is a very com-mon one in physical science. We speak, thus, of the… … Fig. 38. Let Wbe the weight of a body (Fig. 38) resting on aplane HL, and suppose that the plane is inclined at suchan angle (a) that the body is on the point of sliding. 93.] COEFFICIENT OF FRICTION. 97 This angle is called the angle of friction, or angle ofrepose. The force of friction (F),…
