摘要
在弹簧质量和形变不能忽略的情况下,根据最小势能原理和转动惯量的定义,推导出了弹簧在水平面内(忽略重力)做定轴匀速转动时转动惯量的数学表达式.
According to the principle of minimum potential energy and the definition of rotational inertia,the mathematical expression for the rotational inertia of spring uniformly-rotating about a fixed axis in the horizontal plane(ignoring gravity)is deduced in the case when the mass and deformation of the spring can not be neglected.
