WebbAnalogously, 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

Webb8 aug. 2024 · The product of the solutions equals a0, which is also equal to the determinant of the inertia tensor, and the sum of the products taken two at a time equals − a1. We have now found the magnitudes of the principal moments of inertia; we have yet to find the direction cosines of the three principal axes. Webb19 sep. 2014 · 1. The physical significance of non-zero products of inertia is that the chosen axes are not the principal axes of the body. There might be good, solid engineering reason to use those non-principal axes, but that's a question of engineering rather than physics. – David Hammen. Sep 19, 2014 at 12:56.
