静定结构的内力求解是材料力学的重要内容,应用比教学研究方法发现了求解平面静定结构各内力分量的一种通式表达。给出了内力通式表达的结构,并举例与教材中已有做法进行对比,体现出其综合、简洁、实用之处,并于教学实践中取得了良好的效果。所得结论可以作为教学实践的参考。

Solution of internal force of statically determinate structure is the important content of mechanics of materials .During the practice of teach ,we find out a general formula on solution of internal force . Give an example to make contrast between teaching material and the new theory, find out that the formula that we find is simple and practical. It made a good effect during teaching practice. It is also the Application of Comparative method on Mechanics Teaching.
