[问答题]
The moment of inertix x7ubct4nx 14 (rrdwf6:h;cga of a rotating solid disk r2f;z-)s g ofn 1qykg-about an axis through its center of mas)-qgks2-1ffn;yrg z os 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.
