The moment of inertia of 9inoelo jf .+r5:yy 6lnm1yjn* d 6*dsa rotating soli c9bqfudjyg +25ttlktg7n x:px*--9)nz p.hjd disk about an axis through its center ph+g k t7-nb2*t5 y9t .)jqudl p-fx9z:x jncgof 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.
