Question:

The motor turns the disk at the constant speed p = 30 rad/sec. The motor is also swiveling about the horizontal axis B-O (y-axis) at the constant speed θ˙ = 2 rad/sec. Simultaneously, the entire assembly is rotating about the vertical axis C-C at the constant rate q = 8 rad/sec. For the instant when θ = 30°, determine the angular acceleration a of the disk and the acceleration a of point A at the bottom of the disk. Axes x-y-z are attached to the motor housing, and plane O-x0-y is horizontal.
