材料力学课程中杆件内力的教学研究

在材料力学课程教学实践中，为了帮助学生总结和系统化所学知识，从学生需要掌握杆件内力的知识点出发，总结得到快速计算杆件内力以及快速绘制对应的内力图的方法，并且提炼出便捷的助记口诀，在教学中取得了较好的效果。

Research in the Teaching of the Internal Forces of the Bar in the Course of Mechanics of Materials

In the teaching practice of the course of mechanics of materials, in order to help students summarize and sys- tematize what they learned, from their students＂ standpoint, we sum up the methods of rapidly calculating the internal forces of the bar and rapidly drawing the graph of the counterpart force and find a convenient pithy formula to achieve good teach- ing results.
