在高中物理竞赛中常遇到静力学问题,计算量比较大,将常规方法与应用摩擦角和全反力解题进行比较,便体现应用摩擦角解题的优势。
In the high school physics competition often encountered static problems, the calculation is relatively large, the conventional method and the application of friction angle and total reaction problems are compared to embody the advantages of friction angle problem solving.
