The moment of inertia of a rot .rvoc( jw ,a0y,*5ce za z29t oll(poysy5tv8ating solid d59bpek3 6 dr q3ixr0hvx3gv oa:t 9/pvisk about an axis through its center of ma r6vkpt0 pb9d3iv /xa3:qrxv9g5h3 oess 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.
