Unformatted text preview: f, which must be balanced by the friction force f, for steady motion, and measure the resultant steady relative velocity, we can plot the friction coefficient (f,/f,) as a function of relative velocity (see Fig. 2.2.9). The quantity z, is the coeffi-cient of static friction and ,p is the coefficient of sliding friction. When we Friction coefficient= -fn-Ms 10 d(X2 -1) = relative velocity dt Fig. 2.2.9 Typical coulomb friction characteristic. * See, for example, G. W.
