[问答题]
The moment of inertia 0s if4va7eu *racr;h; of a rotating solid ximzr w 1j /vfh*t 73f+51xmzxdisk about an axis through its center of i5j1+x1ffz 3vtmh 7x /zxr *wmmass 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.
