The perpendicular axis theorem for any rigid body

Ana Maria Senra Breitschaft Valmar Carneiro Barbosa About the authors

We present the general form of the perpendicular axis theorem, which can be applied to any rigid body, and we obtain its version valid for any solid of revolution. We also present a particular case for right general cylinders. Some examples are given in order to show how the determination of moments of inertia of certain rigid bodies can be simplified if we use this theorem.
