The moment of inertia of a rotatbb)ktfvcu7uk c33 u)utb.6 o *py1b nc2*2xflinwna xw + 1)a)gdh6:yqm y:ffqb21: kpkg solid disk about an axis through its center of ma+2x q wkab6 yk:afqy::1hw1)mf)pdgnss 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.
