摩擦角与摩擦自锁的一般性解释

A general explanation of friction angle and friction self-locking

从分析物体接触相互作用出发,讨论了摩擦角的概念,并按照摩擦平衡问题推导出摩擦自锁的条件,使学生更容易对这两个概念建立一般性的理解,达到灵活运用理论力学知识的目的。

Starting from the interaction of objects, it disusses the concept of friction angle. In accordance with the balance, it derives friction self-locking conditions. Thus, it helps students more likely to build a general understanding on the two concepts and to achieve the purpose of flexible using the theoretical mechanics knowledge.
