New and Improved SI Edition•Uses SI Units Exclusively in the TextAdapting 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 IllustratedThe 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. Whats New in the Third Edition:Covers life cycle engineeringProvides a description of the hardness and common hardness testsOffers an inclusion of flat groove stress concentration factorsAdds the staircase method for determining endurance limits and includes Haigh diagrams to show the effects of mean stressDiscusses typical surface finishes in machine elements and manufacturing processes used to produce themPresents a new treatment of spline, pin, and retaining ring design, and a new section on the design of shaft couplingsReflects the latest International Standards Organization standardsSimplifies the geometry factors for bevel gearsIncludes a design synthesis approach for worm gearsExpands the discussion of fasteners and weldsDiscusses the importance of the heat affected zone for weld qualityDescribes the classes of welds and their analysis methodsConsiders gas springs and wave springsContains the latest standards and manufacturers recommendations on belt design, chains, and wire ropesThe text also expands the appendices to include a wide variety of material properties, geometry factors for fracture analysis, and new summaries of beam deflection.
