Moment of Inertia: Wheel and Spokes 

Physics Ninja looks at calculating the moment of inertia of a wheel with 3 spokes. The moment of inertia is calculated about three different axes. The first case we consider the moment of inertia through the center of mass of the system. In the second and third case we use the parallel axis theorem to calculate the moment of inertia through axes located on the rim of the wheel.
