【 摘 要 】

This paper presents an improved method of positive assumption for internal force solving, and the application process of this improved method is introduced by some examples, matters to be noted in teaching by this improved method are also analyzed. Teaching practice shows that using improved method of positive assumption to solve internal force, can effectively reduce the error rate, improve the students' ability to analyze the internal force, increase the confidence in mechanics of materials learning, and can produce positive transfer effect for subsequent rated courses learning.
