[问答题]
The moment of inertia of a r/j:us-t h oa2)1 xjjgpotating solid disk about an agm/30 ffr8yj5pzl7 r0oq h k5 9t3bchixis through its center of h53i fckhltqy r80r fgz/ bo50m3j7p9mass 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.
