| 摘 要： | 从圆柱体在斜面上的基本受力分析入手,推导圆柱体沿斜面运动过程中的发生滚动的临界角及滚动摩擦系数的关系式。并通过简单的实验装置测定了铁质圆柱体与玻璃的滚动摩擦系数和静摩擦系数分别约为0.0921和0.121。理论与实验结果基本符合,表明该实验方法对于测定静摩擦系数和滚动摩擦系数的有效性,也为力学基本问题的研究提供了方法。

| Abstract: | The relational formulae between the critical angle of cylinders and the rolling friction coefficient are derived by analyzing the loaded force of the cylinder on the incline.The rolling and static friction coefficients of between the iron cylinder and glass plate was measured by a simple experimental instrument,which are about 0.0921 and 0.121,respectively.Good agreement is achieved between the experimental results and the theoretical ones,indicating that it is effective for the measurement of the rolling friction coefficient and static friction coefficient by this method and providing a new approach for studying the basic problems of mechanics. |
