The figure below gives the moment of inertia Io for a point mass rotating about point O. As a reference, the figure also shows the moment of inertia of a sphere of radius R with respect to the center of mass "G". Suppose that instead of a point mass, a sphere of radius R is now in rotation about a fixed point O a distance R from its center of mass. Identify the moment of inertia Io of the sphere about the point O. Sphere R G IG = mR Mass rotating about point O lo = mR R I = mR 1 mR - 23 I0 = mR mR I = mR + mR I = mR + } { mR ?
