Abstract Mechanics course for engineering students to contact with the early engineering practice related to the basic courses, in order to better understand the follow-up courses and learn more practical problems to provide mechanical theory guidance. In order to simplify the understanding of the content of the mechanics course, proficiency in the application of mechanics in the course of knowledge to explore a better mechanics of epistemology.

In this paper, we mainly study the similarities and differences between material mechanics and elastic mechanics, the rapid internal force diagram in material mechanics and structural mechanics, and the comparison of different methods for solving the consent problem in material mechanics and structural mechanics. This paper summarizes and summarizes the contents of the mechanics course from the basic principles, calculation and analysis, so as to deepen the understanding and understanding of some problems in the mechanics course, and make better use of the knowledge applied to the real life. To achieve the effect of learning to use.

Key words: material mechanics; elastic mechanics; structural mechanics
