MomentOfInertia
MomentOfInertia[reg, pt, v] computes the moment of inertia for the region reg rotating around an axis through the point pt in direction v.
MomentOfInertia[reg] computes the moment of inertia matrix for the region reg relative to the center of mass.
MomentOfInertia[reg, pt] computes the moment of inertia matrix relative to the point pt.
