Mechanical engineering textbook case of: deputy editor in March Democratic compiled SUN Zhao Chunxiang red Publication date: 2013
Series items: Introduction to the "Twelfth Five-Year Plan" textbooks for general higher education "12th Five-Year Plan textbooks for general higher education: Casebooks for engineering mechanics" is divided into 16 chapters, that is, the basics of statics, the Department of Plane Convergence, and the Plane Force couple system, plane arbitrary force system, application of statics in engineering, basics of material mechanics, axial tension and compression, shear and extrusion, section geometry, torsion, bending internal force, bending stress, bending deformation, stress state Analysis, bar stability and material mechanics experiments. Each chapter of the "Twelfth Five-Year Plan" for General Higher Education: Casebooks for Engineering Mechanics consists of five parts: learning points, main text, summary of this chapter, thinking questions, and exercises. Before studying each chapter, you can understand the main content of this chapter by reading the learning points, thereby enhancing the initiative and enthusiasm of learning; the summary of this chapter is the summary, induction and extraction of the content of this chapter, so that the knowledge learned is more physical and systematic, so that Further deepen the understanding and understanding of the content; thinking questions and exercises can deepen the understanding and mastery of the knowledge learned, and can improve the ability to use knowledge flexibly. The "Twelfth Five-Year Plan" textbooks for general higher education: Casebooks for engineering mechanics can be used as textbooks for engineering mechanics courses for engineering undergraduates in colleges and universities. Self-study exam reference.
