Design of Machine and Structural PartsA fully developed and very practical presentation of the subject of form design of machine components is provided in this book, including how to recognize what form or shapes cause what stress patterns and how to apply the information to an overall design. Techniques are presented that guide the design engineer to the correct kind of element to use without the need of calculations; how to choose shapes that produce efficient stress patterns. Also included is a brief review of strength/design procedures; the nature of efficient and inefficient stress patterns are covered, general principles of component design, optimizing strength-to-weight ratios, considerations for buckling and impact and the design of joints. |
