摘要: 一段均质圆弧绕弧上一铰接点摆动即形成一个圆弧摆,通过本文的研究,发现此类圆弧摆的周期,均可用自然悬挂时过质心的弦所构成的圆弧摆作微小摆动时之简谐运动的周期表示.

关键词: 圆弧摆, 周期, 弦长

Abstract: The period of arc swing,which is formed by a homogeneous arc swinging around a random point on the arc,is generally studied. The periods of both expressions are given by the crossing centroid or geometrical factors.

Key words: arc swing, period, length of chord
