Consider a flat rigid body lying in the xy plane as shown in the figure. If the moment of inertia about the Z' axis (perpendicular to the xy plane) passing through the center of mass (CM) is ICM, then the moment of inertia about the Z axis perpendicular to the xy plane (thus parallel to the Z' axis) through the point P at a distance of d from the CM. Show = m? F.² that the moment of inertia I, (approximating a continuum rigid body as a collection of small mass elements m.) is equal to ICM +MD (Use ?m. r=0 .) Z 7 PR d ?í CM
