Of Engineering Mechanics: Chen Yunxin edited publication time: 2013
Brief introduction of the content "Engineering Mechanics" is based on the requirements for talent training in the 21st century and the directive spirit of the Ministry of Education on the reform of the teaching content and curriculum system facing the 21st century. It draws on the characteristics of some excellent teaching materials at home and abroad and is based on many years of teaching practice. Made of. This textbook integrates basic mechanics knowledge such as theoretical mechanics, material mechanics, and structural mechanics, selects classic content, and combines it with relevant professional requirements such as industrial design, architecture, transportation engineering, and environmental engineering. It is refined and innovative. This book is divided into 14 chapters: Chapter 1 is the introduction; Chapters 2 to 5 study the law of balance of rigid bodies, focusing on static analysis, equilibrium conditions and their applications in practical engineering; Chapter 6 is for plane systems. Analysis of geometric composition and calculation of internal force of statically determinate truss; Chapters 7 to 14 mainly introduce the relevant content of material mechanics, study the strength, stiffness and stability of deformed solids under normal working conditions; Geometrical properties, beam deformation under simple load, commonly used section steel specifications. After each chapter, an appropriate amount of thinking questions and exercises are configured to help students learn to master relevant knowledge. Engineering Mechanics can be used as a teaching material for engineering mechanics courses for undergraduates majoring in architecture, urban planning, transportation engineering, industrial design, engineering management, environmental engineering, water conservancy and hydropower engineering, packaging, etc. It can also be used for higher vocational colleges, adult education, and the Internet. References for education, college teachers, and related engineering and technical personnel. This book is edited by Chen Yunxin.
