[问答题]
The moment of inertia of a rotatig0; y6)djqpn 4 qrxk)xza6e *e;ojnp4n n30rtyy0gu q7, b+ezwg solid disk about an axis through its center of mass is y3 7zre 0,qun+wytg0 b$\frac{1}{2}WR^2$ (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.
