Problem 2: Ring B has an inside radius r2 and hangs from the horizontal shaft A as shown. Shaft A rotates with a constant angular velocity of 25 rad/s and

no slipping occurs.Knowing that ri = 12 mm, r2determine (a) the angular velocity of ring B, (b) the accelerations of the points of shaft A and ring B which are in contact, (c) the magnitude of the acceleration of a point onthe outside surface of ring B.30 mm, and r33= 40 mm,
