接續1的証明,証平行軸定理(parallel-axis theorem)。相关知识点: 试题来源: 解析 平行軸定理的證明如下:設物體質量為M,質心軸轉動慣量為I_cm。另有一平行軸,距離質心軸為d。物體上任一質點dm到質心軸的位移為r,到新軸的位移為r'。由幾何關係得r' = r + d,其中d為兩軸間位移向量。則新軸轉動慣量為:I ...

The moment of inertia is at a minimum value when it is closest to the center of mass. If you transfer the axis of rotation elsewhere, it becomes more difficult to slow down or speed up. This increases the moment of inertia. Applying the Parallel-Axis Theorem ...

平行轴定理提供了一种方便快捷的方法,可以求物体绕平行于通过其质心的轴的轴的惯性矩。以一根细棒为例。使用传统方法寻找细棒绕穿过其中间(质心所在)的轴的惯性矩的过程与寻找穿过其末端的轴的过程之间存在惊人的相似之处。在传统方法中,利用了线性质量密度和沿杆长度的积分的概念。假设要确定这根细棒绕一端旋转...
