Moment of Inertia for a cylinder
This page discusses the moment of inertia specifically in the case of a ring
Written by Jack Corelli
The Main Idea
See The Moments of Inertia for a more general explanation of moments of inertia.
The moment of inertia of an object relates the mass of the object, the distance between the center of mass and the shape of rotation. In a ring, or uniform loop, the center of mass is exactly at the center of the ring, and the moment of inertia can be found by approximating the exterior ring as a single line, akin to a circle.
