The solid circular disk of mass m and small thickness is spinning freely on its shaft at the rate p. If the assembly is released in the vertical position at determine the horizontal components of the forces A and B exerted by the respective bearings on the horizontal shaft as the position is passed. Neglect the mass of the two shafts compared with m and neglect all friction. Solve by using the appropriate moment equations.
