f inertia of a lamina about an axis which is per-pendicular to its plane equals the sum of the moments of inertiawith respect to two rectangular axes which lie in the plane ofthe lamina with their origin on the first axis. Suppose the lamina to be in the xj/-plane, then the theo-rem states that the… … CENTER OF MASS AND MOMENT OF INERTIA 155 It is evident from this theorem that when the lamina isrotated about the s-axis I^ and /„ change, in general, buttheir sum remains constant. 122. Theorem II. — The moment of inertia of a body aboutany axis equals its moment of inertia about a parallel…
