The 10.2-ft steel beam is being hoisted from its horizontal position by the two cables attached at A and B. If the initial angular accelerations are α1 = 0.52 rad/sec2 and α2 = 0.35 rad/sec2 , determine the initial values of

(a) the angular acceleration α (positive if counterclockwise, negative if clockwise) of the beam,
(b) the acceleration of point C (positive if up, negative if down), and
(c) the distance d (positive if to the right, negative if to the left) from A to the point on the centerline of the beam which has zero acceleration.
