Shigley’s Mechanical Engineering Design, Eighth Edition Budynas−Nisbett

Shigley’s Mechanical Engineering Design,

Eighth Edition

Budynas−Nisbett

This eighth edition contains the following significant enhancements:
• New chapter on the Finite Element Method. In response to many requests from reviewers, this edition presents an introductory chapter on the finite element method. The goal of this chapter is to provide an overview of the terminology, method, capabilities, and applications of this tool in the design environment.
• New transmission case study. The traditional separation of topics into chapters sometimes leaves students at a loss when it comes time to integrate dependent topics in a larger design process. A comprehensive case study is incorporated through standalone example problems in multiple chapters, then culminated with a new chapter that discusses and demonstrates the integration of the parts into a complete design process. Example problems relevant to the case study are presented on engineering
paper background to quickly identify them as part of the case study.
• Revised and expanded coverage of shaft design. Complementing the new transmission case study is a significantly revised and expanded chapter focusing on issues relevant to shaft design. The motivating goal is to provide a meaningful presentation that allows a new designer to progress through the entire shaft design process – from general shaft layout to specifying dimensions. The chapter has been moved to immediately follow the fatigue chapter, providing an opportunity to seamlessly transition from the fatigue coverage to its application in the design of shafts.
• Availability of information to complete the details of a design. Additional focus is placed on ensuring the designer can carry the process through to completion. By assigning larger design problems in class, the authors have identified where the students lack details. For example, information is now provided for such details as specifying keys to transmit torque, stress concentration factors for keyways and retaining ring grooves, and allowable deflections for gears and bearings. The use of internet catalogs and engineering component search engines is emphasized to obtain current component specifications.
• Streamlining of presentation. Coverage of material continues to be streamlined to focus on presenting straightforward concept development and a clear design procedure for student designers.
