摘要： 质量均匀分布的链条，两端合在一起，以一定角速度绕竖直轴旋转，会呈现泪滴状.两端竖直分开距离和旋转角速度

在一定范围内，旋转链条会呈现倒放的心形.实验图像与理论曲线一致.

Abstract: A uniform mass distributed rotating chain can take a teardrop configuration with both ends fixed at

the same point. It also can take an upside down heart like configuration with two ends fixed separately in a vertical

rod when the angular velocity and separated distance are well chosen. The experimental figures agree well with the

theoretical curves.

Key words: rotating catenary, teardrop
