The 250-mm uniform rod BD, of mass 5 kg, is connected as shown to disk A and to a collar of negligible mass, which may slide freely along a vertical rod. Knowing that disk A rotates counterclockwise at a constant rate of 500 rpm, a) Determine the velocity of the collar D and the angular velocity of the rod BD. b) Determine the acceleration of the collar D and the angular acceleration of the rod BD. c) Determine the acceleration of point G, the center of mass of the rod BD d) Determine the reaction at D when 0 = 0.
