[问答题]
The moment of inertia of a4np, .fa;y0 libwv -pg rotating sol/dm t ybiy(i2+eq6z v13rp4glid disk about an axis through its center m 6q d( pg+/i1 vbl2e4ryz3tyiof mass 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.
