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 WebApr 7, 2024 · The moment of inertia is alternatively called angular mass, and its SI is kg.m2.
