[问答题]
The moment of inertia of a rotating solid di+ pq,c t w)-pdb6osza.sk about an d qc)yvv5y9evfs1c:kw+n-; h axis through its center of mass is -d q:+c skchw59fev1;v)y v yn$\frac{1}{2}WR^2$ (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.
