[问答题]
The moment of inertia of a rotatingqn7:ab1egjfo 5q3 tx; solid disk about an axis throu 8o3:qmqs.d21ntmrbx gh its center of mass is bn2s t1 8qq dromm3.x:$\frac{1}{2}WR^2$ (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.
