摘要
平面任意力系的平衡方程及应用是教学的重点和难点,它是解决物体系统平衡问题的基础,学生应理解并熟练掌握。本文举一典型例题来说明平面任意力系的平衡方程的三种形式的具体运用。
The equilibrium equations and application of coplanar arbitrary forces is key teaching points and difficult points. It is the basis to solve the equilibrium problem of an object system. Students should un- derstand and master it well. We give a typical example to illustrate the concrete application of equilibrium equations of coplanar arbitrary forces.
