Shigley’s Mechanical Engineering Design is a standard text intended for beginners of the subject area. This revised edition in SI units focuses on blending fundamental concepts with modern emphasis on design and new applications. It covers the basics of machine design, including the design process, engineering mechanics and materials, failure prevention under static and variable loading, and characteristics of the principal types of mechanical elements. As an indispensable reference text, it makes students familiar with the basis for decisions as well as the standards of industrial components and helps them transition into practicing engineers. Updated and revised chapters on Fatigue Failure Resulting from Variable Loading and Lubrication and Journal Bearings. Expanded coverage of plastic deformation, strain hardening, true stress and strain, and cyclic stress strain properties and Rich pedagogy.
