WebJul 14, 2024 · For a uniform, regular (and solid) tetrahedron described, the moment of inertia about any axis which passes through the center of mass is equal. Rotationally, this is what defines a circle, so this is my translation of “it is sphere”. To make life easy, I’d like to define the origin to coincide with the center of mass. WebProblem.
