The moment of inertia of 7vy-gbe d ;n8ca rotating solid dhzl4 :.zu d6f0 fg7huqm tt-nh 5org38isk about an axis through its center ozm3 t8hzhuf7-ghgrq0dtf65 .ln :4o uf 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.
