Solve the below problem:
Q: A disk of 9-in. radius rotates at the constant rate ω2 = 12 rad/s with respect to arm CD, which itself rotates at the constant rate ω1 = 8 rad/s about the Y axis. Determine at the instant shown the velocity and acceleration of point A on the rim of the disk. You should solve the problem step by step.
