[问答题]
The moment of inertia of a rotating soli / fl) vyl(a.snx k0wsx/w3 z.fd disk about an axis 5f.vooqr, s, jcx,e w0msjt,*through its center of mass is jj,.ts,m ver* cxq0o,5fows, $\frac{1}{2}WR^2$ (Fig. 8–21c). Suppose instead that the axis of rotation passes through a point on the edge of the disk. Will the moment of inertia be the same, larger, or smaller? 
参考答案: The moment of inertia will
increase, because most the mass of the disk will be further from the axis of
rotation than it was with the original axis position.
