...perpendicular-axes theorem 1. If I x and I y are the mass moments of inertia of a rigid plane lamina about any pair of orthogonal axes in its plane, then the mass moment of inertia I z about the z -axis (the polar moment of inertia ) is given by I z = I x + I y . 2. If I x and I y are the second moments of area of a rigid plane lamina about any pair of orthogonal axes in its plane, then the second moment of area J about the z -axis (the polar second moment of area ) is given by J = I x + I y . See also parallel-axes theorem...
