The 20-kg steel ring A with inside and outside radii
of 50 mm and 60 mm, respectively, rests on a fixed
horizontal shaft of 40-mm radius. If a downward
force P = 150 N applied to the periphery of the ring
is just sufficient to cause the ring to slip, calculate
the coefficient of friction u and the angle 0.
