The moment of inertia of a rotatini* ejoc.zv-lm3fw3b2 g solid disk about an axis: iratn/ed1-rpuyge1( pt( g ; through its center of mas(ggd:ey/1(;r-et1ipnr pta us 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.
