这项工作的重点是一个著名的惯性演示的理论分析，它使用了一个由一个额外的字符串，挂在下面的重量的重量。问题的关键是，当以恒定的拉动速度向下拉动下弦的底部边缘时，上弦或下弦中的哪一根会断裂。运动方程的解析解使我们能够确定拉动速度的临界值，超过该临界值，琴弦的断裂就会发生变化。分析还为我们提供了一个相图，说明了在拉或拉实验中拉速和弦的弹性之间的相互作用。
This work focuses on a theoretical analysis of a well-known inertia demonstration, which uses a weight suspended by a string with an extra string that hangs below the weight. The point in question is which string, the upper or lower, will break when pulling down on the bottom edge of the lower string at a constant pulling speed. An analytic solution for the equation of motion allows us to identify the critical value of the pulling speed, beyond which the string breaking varies from one to the other. The analysis also provides us with a phase diagram that illustrates the interplay between the pulling speed and the stringʼs elasticity in the pull-or-jerk experiment.
