[问答题]
The moment of inertia of a rotating solid disk about an i,vb8i,7t 0exx i; 1dxwzh8hxaxis pfv, mxrtf*)ha2p 6g 7ng1cc2 through its center of mast) cpaf6 v,mfrnx2 cg7g*hp12s 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.
