Webb23 dec. 2024 · You will not find tables of products of inertia because it is not necessary to know them. The moments of inertia for any rigid body about any axis can be calculated … WebbThe first integral is the product of inertia I x'y' of the area A about the centroidal axes, x' and y' . The second an third integrals are the first moment of the area A about the centroidal axes, x' and y' and the value of the first moment of the area about the centroidal axis is equal to zero. The fourth integral is equal to the total area only.
