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
