Question:

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 r1 = 12 mm, r2 = 30 mm, and r3 = 40 mm, determine 

(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 point D
