[问答题]
The moment of inertia of a rotating solid disk about d8-qd14xzfx3v).mtqg(qb e wan axis through p/j viyb1,ey0 its center of mass iyj ievb0y/, p1s $\frac{1}{2}WR^2$ (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.
