| 摘 要： | 正确绘制物体受力图是学好工程力学的基础,也是解决工程中力学问题之关键。学生在学习此章节时,往往采用物理学中画受力图的方法来进行受力分析,从而导致作图错误。文章主要从改变传统四步作图法着手,通过对杆件受力的分析与研究,让学生掌握绘图的分析技巧,以达到快速掌控绘制受力图之目的。

| Abstract: | Drawing object＇s free-body diagram is the first step to study engineering mechanics,and in fact,it is a crucial step in solving related problem.While learning,the students often can not quickly grasp the essentials of drawing,thus resulting in drawing errors.In order to solve this problem,the paper introduces the drawing skills to master drawing method of object＇s free-body diagram by changing the traditional drawing method. |
