Abstract

A tangential force, FT, is required to start the relative motion between two bodies kept in close contact by a normal force FN (Fig. 2.1a). Such a force is called friction force and is required to overcome the static friction force, Ff, which opposes the motion. The ratio FT/FN = μs is the coefficient of static friction. In general, μs is independent from the nominal area of contact while it can depend on FN and on the properties of the mating materials and their surfaces.
