摘要: 给出悬挂重物的绳子在稳定转动状态下的线元方程,通过数值计算,得出绳子能弯曲稳定转动的角速度特征值.并讨论了这个特定值和悬挂重物质量的关系,还将实验图形和理论图形做了对比.

关键词: 绳子, 转动, 角速度

Abstract: The equation of rotating rope with an object hanging on the end in the stable state is derived.The normal angular speed under which the rope can rope stable is calculated numerically under the boundary conditions.The dependence of normal angular speed on the mass of hanging object is discussed.The comparison between theoretical and experimental figures is also performed.

Key words: rope, rotation, angular speed
