Typically for third year college courses in Machine Design, Design of Machine Elements, and Mechanical Design in Engineering and Engineering Technology programs. This book provides a practical approach to designing machine elements in the context of complete mechanical design. This edition retains many features of the previous edition--exceptional organization, readability, practical approach, sound technical content, extensive appendix, design procedures, example problems, use of computer aids, and use of many examples from commercially available products and systems--yet, has been extensively updated to include new photographs; new design data for some elements; new or revised standards; new end-of-chapter references; listing of internet sites; and some completely new elements.
