Providing the bridge between analysis and design functions, this extensively rewritten and updated Third Edition of a time-tested text helps students recognize and approach design problems with the most recent and appropriate theories and techniques-detailing the product and system design process from conceptual, economic, and ethical considerations to modeling, decision making, and testing. Enables the engineering educator to satisfy the requirements of the Accreditation Board for Engineering and Technology (ABET) for the design component of engineering curricula and contains end-of-chapter review exercises, incisive discussions, and helpful practice projects that give students the hands-on design experience essential for product and system innovation Reinforced with practical examples throughout, the Third Edition features expanded coverage of product liability-examining warning labeling, design review and checking, and guidelines for the engineer as expert witness engineering standards-introducing a simple and quick method of locating U.S. and foreign standards patents-describing modern search procedures, changes in patent law, and other forms of intellectual property and their protection system design-exploring nonengineering aspects of system use, such as legal, medical, and sociological implications computer-aided design (CAD)-furnishing a new list of commercially available general purpose programs and an improved review of finite element analysis and expert systems optimum design-presenting novel computer search techniques and elucidating optimization with computer-aided engineering (CAE) systems reliability-highlighting equations for calculating reliability and effects of early and end-of-life failures as well as advantages of Weibull functions and more Enhanced with over 200 tables, drawings, and photographs-numerous new to this edition-Design of Devices and Systems, Third Edition serves as an excellent textb
