The motor of Sample Problem 7/2 is shown again here. If the motor pivots about the x-axis at the constant rate rad/sec with no rotation about the Z-axis (N = 0), determine the angular acceleration α of the rotor and disk as the position γ = 30° is passed. The constant speed of the motor is 120 rev/min. Also find the velocity and acceleration of point A, which is on the top of the disk for this position.
