Moments and Product of Inertia |
Thus, Izz = Iz'z' + Md2 Similar thing will hold good for the moment of inertia about other axes. Thus, the moment of inertia of a body about any axis equals the moment of inertia of the body about a parallel axis that goes through the center of mass, plus the total mass times the perpendicular distance between the axes squared . For the product of inertia, a similar relation can be reached. For Ixy , for example, we have Ixy = Ix'y' +Mxcyc
