The moment of inertia z dp 7);4: mesdag(xqbof a rotating solid sg8a 3o9fx90psn mb 5mdisk about an axis through its center of mass if9 0p5s gsm xmo3a9b8ns $\frac{1}{2}WR^2$ (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.
