The body of knowledge of engineering mechanics consists of two parts: statics and mechanics of materials.
The main contents of statics are the basic knowledge of statics and plane force system. The basic knowledge of statics includes forces and the force system, fundamental theorems of statics, the synthesis and decomposition of forces, couple and moment of couple, restraint and constraining force, force analysis of object, calculation sketch of structure, geometric composition analysis of plane system. the plane force system includes plane concurrent force system, plane parallel force system, plane system of couples, plane arbitrary system of force, equilibrium of the object system, and friction equilibrium problem. The main task of statics is to apply the principles of force calculation, basic laws and equilibrium conditions to solve the external load situation of the structure in the process of bearing and transferring forces.
The main contents of mechanics of materials are the Basic Knowledge of Material Mechanics, geometric properties of plane figures, internal forces, stresses, strength, deformation, strain, stiffness series of contents in axial tension and compression, shear, bending, torsion and combined deformation of rods, and compression rod stability. The main task of the mechanics of materials is to apply the internal state of forces of the structure to solve the strength, stiffness and stability of the rod.
Through the systematic study of engineering mechanics, students can analyze and solve the load-bearing capacity problems of structures in actual projects on the basis of mastering the external loading conditions and internal force states of structures. At the same time, it also lays the foundation for the design research and optimization innovation of engineering structures. In the study of mechanics with logical thinking and systematic awareness, students will not only gradually cultivate the craftsmanship spirit of excellence and determination, but also help students to establish a scientific rigorous and pragmatic academic attitude.
Engineering mechanics is a very vital discipline with a wide range of applications.
