Of Engineering Mechanics: Wei forward Published: 2013
Introduction to the content "Engineering Mechanics" edited by He Wei et al. Is based on the basic teaching requirements of engineering mechanics courses (medium and junior hours) in colleges and universities of the Ministry of Education and the actual implementation of engineering mechanics courses in universities nationwide. The results of teaching reform of engineering mechanics strive to reflect the content from shallow to deep, knowledge points back and forth, and pay attention to the focus and relationship of statics and material mechanics, highlighting the comprehensive application of theoretical knowledge and the cultivation of computing skills. Questions and exercises are set after each chapter, and some questions and answers are attached, which is convenient for students to review and consolidate in time. "Engineering Mechanics" can be used as a teaching material or teaching reference book for environment, transportation, materials, geology, industrial management, metallurgy and electromechanical majors, as well as reference for related engineering and technical personnel.
