论文摘要
在理想的绳子和大型皮带轮之间的接触线上弦张力的分布是一个经常讨论但不完全解决的问题,使学生面临入门力学的学生。我们通过大量的Atwood的机器在通常呈现此问题的情况下强调了歧义,并讨论了两种紧凑的分辨率,这些决议可以治疗皮带轮或绳子弹性变形的情况。我们提出的实验可以在中间实验室中开发,以确定张力谱。
The distribution of string tension on the contact line between an ideal string and a massive pulley is a frequently-discussed but incompletely-posed problem that confronts students in introductory mechanics. We highlight ambiguities in the usual presentation of this problem by the massive Atwood's machine and discuss two compact resolutions that treat situations where the pulley or the string elastically deform. We propose experiments that can be developed in an intermediate laboratory to determine the tension profile.
