[问答题]
The moment of inertia of a rotating solid disk as p-xs98io4.6orr sed bout an axis through itsc,vg7 hgr7 .c:w*kuwq center of mcw* ug k.gqc7r v,:w7hass 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.
