Publication time of the new engineering mechanics foundation: 2012 Content introduction "The new engineering mechanics foundation" is the fruit of the teaching reform of the engineering mechanics course in elementary and middle school hours. The first and second editions of the multi-hour textbooks "Engineering Mechanics Fundamentals (Ⅰ)" and "Engineering Mechanics Fundamentals (Ⅱ)" edited by the editor have been included in the "Tenth Five-Year" national planning textbooks for general higher education and the "Eleventh Five-Year Plan" "National Planning Textbook. In the process of writing this book, full consideration was given to the mathematical and physical foundations of related major students, the requirements of professional training objectives for students' mechanical abilities, and the widespread impact of computers and the large-scale application of commercial software on the mechanical foundation and ability requirements of engineering and technical personnel. The choice of teaching content follows the principle of "broad and shallow", that is, to retain a wide range of knowledge, focusing on the introduction of basic concepts, basic theory and basic methods of engineering mechanics, engineering applications of mechanics, mechanical modeling and characterization of engineering systems. Analysis, while significantly reducing the content of quantitative analysis and design calculations. Compared with similar textbooks, the difficulty of this book is reduced, and the knowledge is greatly broadened. A large number of engineering-related examples, reflections, and exercises are introduced. The book is divided into four chapters and 14 chapters covering the basics of static analysis, the basic concepts, methods, and theories of material mechanics, the analysis of the strength, stiffness, and stability of rods, and the basics of motion analysis. Basic content, as well as the D'Alembert's principle and dynamic and static methods in dynamics related to the dynamic load of material mechanics. This book can be used as engineering (undergraduate) engineering design, engineering management, automation, electrical engineering and its automation, measurement and control technology and instruments, numerical control technology, materials science and engineering, polymer materials and engineering, architecture, building environment and Textbooks for equipment engineering, safety engineering, etc., and can be used as reference books for higher vocational colleges, adult education colleges, and related engineering and technical personnel.
