A 20 lb uniform disc A is pinned to a 4 lb uniform rod CB which is pinned to a 0.03106 slug collar C. C slides on a smooth vertical rod and the disc rolls without slipping. Determine: a) the angular acceleration ofA and the acceleration of C when released from rest and b)The velocity of B and C when the rod is horizontal.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
