The moment of inertia of a rotati5l,v/ ztbfp *q0fsi:htl4 :;gejg bv7kwr5o + ng solid disk about an axis through its center oflhi:wt4k gse:bf 7 05+o; gjvr 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.
