The moment of inertia of a rotating 1mag:,(6h4w n c6mtpcnb d6 xksolid disk about an axis through its cl -q*c-zczr v:,yyzil +t9/ ssenter of mass c,s-ll-+9is ryqz : z/tvycz* 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.
