The approximate linear model of the three-string pendulum and its computational formula for the moment of inertia are discussed.

对三线摆的线性近似模型和转动惯量计算公式的由来作了简要说明。

This concept was based on the n ive notion that the pendulum would "fall over" as the rocket turned at the peak of the trajectory.

这个概念的基础上， n ive概念，即钟摆会"跌倒"作为火箭拒绝在高峰期的轨迹。

The present device is also called a conical pendulum.

上述装置也称为圆锥摆。
