Identify how many degrees of freedom there are in the following mechanical systems: (a) a compact disc in use (i.e., a rigid body rotating about a fixed axis-all the points in the body that lie along the axis are not moving), (b) a spinning top (i.e., a rigid body rotating about a fixed point - all the points of the body can rotate except for the point on the body that is fixed), (c) a bug crawling on the ground (i.e., a particle moving on a given surface)
