[问答题]
The moment of inertia of1)atac+;mvh; xq9d bda u3rc+ a rotating solid disk about an axis t a/t2nryfq6yeib 7t( 4hrough its center of ma7fn2ty(6tb yi/4qraess 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.
