WebAnalogously, we can deﬁne the tensor of inertia about point O, by writing equation(4) in matrix form. Thus, we have H O = [I O] ω , where the components of [I O] are the moments and products of inertia about point O given above. It follows from the deﬁnition of the products of inertia, that the tensors of inertia are always symmetric. The WebSep 12, 2024 · The moment of inertia is the quantitative measure of rotational inertia, just as in translational motion, and mass is the quantitative measure of linear inertia—that is, the more massive an object is, the more inertia it has, and the greater is its resistance to change in linear velocity.
