[问答题]
The moment of inertia of a rotating solid disk about phtwe(oi re,aw( 6 2k,an a(s g852( fw4 jfnxq 5vkktvc36ibn0am xis through its center of mass xj v605kt f ns3bq(45w2 cv8kagm( nfiis $\frac{1}{2}WR^2$ (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.
