Lo the ry-plane at the point I = I, + m(x² + y) where I, is the moment of inertia about (0,0). (This is a version of the theorem of paralle mechanics. This theorem, along with a table of moments of inertia for standard shapes gi books, allows us to quickly find the moment of inertia around other axes as needed.)

D. Suppose that the center of mass of a uniform plate is at (0,0), and that the plate has total mass m.
Show that its moment of inertia about an axis perpendicular to the ry-plane at the point (ro, Yo) is
I = 1, + m(r² + v
where I. is the moment of inertia about (0,0). (This is a version of the theorem of parallel axes from
mechanics. This theorem, along with a table of moments of inertia for standard shapes given in most
books, allows us to quickly find the moment of inertia around other axes as needed.)
