由于摩擦角和动摩擦因数有直接关系,教学中适当的引入其性质可以拓展学生思路,帮助学生对受力分析问题有更深入的理解,本文从摩擦角的两个性质出发,以案例的形式分析了摩擦角在五类问题中的应用。
Due to the direct relationship between the friction angle and the dynamic friction factor, proper introduction of the nature of the teaching can broaden the students’ thinking and help students to understand the problem of force analysis more deeply. Based on the two properties of friction angle and the case analysis The application of friction angle in five kinds of problems.
