The kinetic diagram representing the general rotational motion of a rigid body about a fixed axis passing through O is shown in the figure. Show that IGα may be eliminated by moving the vectors m(aG)t, and m(aG)n, to point P, located a distance rGp = k2G/rOG from the center of mass G of the body. Here kG represents the radius of gyration of the body about an axis passing through G. The point P is called the center of percussion of the body.
