[问答题]
The moment of inertia of a rotating solid disk about ye(nxg qcas9v3*gd ,jz:7ttlw*;p ; d an axis through its cent k 4 v2id3j rxvjh+0v;ue79kacer o 4ka;iv9r xvh7d jk02e3cj u+vf mass 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.
