The moment of inertia .jig/*w+r x x6dbizzbbv()z / of a ro(lhd 90eucqw iq1u7-b tating solid disk about an axis through its center of mase ul9q 0d7( qhbwiu1-cs 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.
