[问答题]
The moment of inertia of a rotating solid disk about an axis thro4 r/b dameg7 irlu1u+:/qh5 hwugh its cr -b v90cvq0 p6mogiy3enter of mass iq903b vg-c0myo 6rpv 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.
