New and Improved SI Edition—Uses SI Units Exclusively in the Text

Adapting to the changing nature of the engineering profession, this third edition of Fundamentals of Machine Elements aggressively delves into the fundamentals and design of machine elements with an SI version. This latest edition includes a plethora of pedagogy, providing a greater understanding of theory and design.

Significantly Enhanced and Fully Illustrated

The material has been organized to aid students of all levels in design synthesis and analysis approaches, to provide guidance through design procedures for synthesis issues, and to expose readers to a wide variety of machine elements. Each chapter contains a quote and photograph related to the chapter as well as case studies, examples, design procedures, an abstract, list of symbols and subscripts, recommended readings, a summary of equations, and end-of-chapter problems.

What’s New in the Third Edition:



Covers life cycle engineering
Provides a description of the hardness and common hardness tests
Offers an inclusion of flat groove stress concentration factors
Adds the staircase method for determining endurance limits and includes Haigh diagrams to show the effects of mean stress
Discusses typical surface finishes in machine elements and manufacturing processes used to produce them
Presents a new treatment of spline, pin, and retaining ring design, and a new section on the design of shaft couplings
Reflects the latest International Standards Organization standards
Simplifies the geometry factors for bevel gears
Includes a design synthesis approach for worm gears
Expands the discussion of fasteners and welds
Discusses the importance of the heat affected zone for weld quality
