Solve the below problem:
Q: A 10-kg uniform disk is placed in contact with an inclined surface and a constant couple M is applied as shown. The weight of the uniform link AB is 5 kg and the coefficient of kinetic friction at D is 0.25. Knowing that the angular acceleration of the disk is 16 rad/s2 clockwise, determine
(a) The magnitude of the couple M,
(b) The force exerted on the disk atD.
