[问答题]
The moment of inertia of a r b zq5e )5.nss9gmo-orotating solid disk about an axis through its ioqox w5ors4l0f5t50 xo4 e/k2s n5uhcenter of xi 45q o5 s hlwon2/et455usofkr00ox 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.
