The moment of inertia of a rotating solid disk ab-6r0 zqk2xzmfxoh*(i out an axis through bb(;9wld2fba bcbx, u q))/pnr;a md.its center of mass i; c fpnblu/2;d. dmx bq(a)w,b9rba)bs $\frac{1}{2}WR^2$ (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.
