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 I_Gα may be eliminated by moving the vectors m(a_G)_t and m(a_G)_t to point P, located a distance r_GP = k²_G/r_oG 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.
