[问答题]
The moment of inertia of . w-rdar/ f(1d lr3swoa rotating solid disk about an axis through ith fgcv hgd+ib7guyg+1 0u ein;)pw(34s center of m4u3w hn1igcpgy bi gd7++ )huvge( 0;fass is $\frac{1}{2}WR^2$ (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.
