Again, for the solid pivot (Fig. 4.29, case (a)), writing r 2 =0 as before
(C). Conical pivot uniform pressure
The system analysed is shown in Fig. 4.30. Proceeding as before, the
intensity of the bearing pressure at radius r is determined by the condition
pr = C, so that

Numerical example
Show that the virtual coefficient of friction for a shaft rotating in a V-groove
of semi-angle a, and loaded symmetrically with respect to the groove, is
given by
