The moment of inertia lh or0va* mf)nk:ay2o;xc1 e4ofz *jb(37tz jay kv:)ak th,3he a rotating solid disk about an axis through its center of mass iet*v)yt3h,(ajj z hkb: k37z as $\frac{1}{2}WR^2$ (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.
