摘要
文章基于共振原理,将三线摆和单摆结合起来,利用共振状态下的单摆周期等效于三线摆的周期,将单摆的周期公式代入三线摆求转动惯量的理论推导式中,消掉重力加速度g,达到计算不用考虑g值的目的。
Based on the principle of resonance,the paper combines the three-wire pendulum with the single pendulum,using the single pendulum period in the resonant state to be equivalent to the period of the three-line pendulum.The formula of the one-pendulum periodic formula is substituted into the theoretical derivation of the rotation inertia of the three-line pendulum,and the gravity acceleration g is removed,and the purpose of the g value is not considered.
