[问答题]
The moment of inertia of a rotating solid disk x5hft 79njtu4/ur 4mtabout an axis thrg 3v9ygo b+)gtough its center of mass istgo)+ bgy g93v $\frac{1}{2}WR^2$ (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.
