The history of gears with asymmetric teeth is not sufficiently recorded in modern gear literature, with some gear researchers concluding that asymmetric tooth gears were discovered just several decades ago. This book sheds light upon the origins and state of asymmetric gearing, referencing technical articles from the 19th, 20th, and 21st centuries. As a practicing gear engineer with nearly 40 years’ experience, author Alex Kapelevich has successfully implemented asymmetric gears in a variety of custom gear transmissions. This book addresses all aspects of asymmetric gear development, including theoretical fundamentals; tooth geometry optimization; stress analysis and rating; design and production specifics; analytical and experimental comparison to the best symmetric gears; and application examples. Readers are encouraged to look beyond the status quo established by traditional gear design, and to apply principles of asymmetric gearing to actual gear design. Optimal solutions are presented for gear drives that will maximize technical performance and marketability.

Thermodynamics, An Engineering Approach, eighth edition, covers the basic principles of thermodynamics while presenting a wealth of real-world engineering examples so students get a feel for how thermodynamics is applied in engineering practice. This text helps students develop an intuitive understanding by emphasizing the physics and physical arguments. Cengel and Boles explore the various facets of thermodynamics through careful explanations of concepts and use of numerous practical examples and figures, having students develop necessary skills to bridge the gap between knowledge and the confidence to properly apply their knowledge. Thermodynamics is now presented in full, four-color design. The illustrations and photographs are now more realistic and offer increased understanding to the student. Some of the figures and photographs in the text are intended to serve as a means of emphasizing key concepts that would otherwise go unnoticed. This edition includes over 500 new problems and a significant number of the existing problems are modified. An important change is the update of the R-134a tables to make property values consistent with those from the latest version of EES (Engineering Equasion Solver). All the solved examples and end-of-chapter problems dealing with R-134a are modified to reflect this change.

The latest edition of Juvinall/Marshek’s Fundamentals of Machine Component Design focuses on sound problem solving strategies and skills needed to navigate through large amounts of information. Revisions in the text include coverage of Fatigue in addition to a continued concentration on the fundamentals of component design. Several other new features include new learning objectives added at the beginning of all chapters; updated end-of-chapter problems, the elimination of weak problems and addition of new problems; updated applications for currency and relevance and new ones where appropriate; new system analysis problems and examples; improved sections dealing with Fatigue; expanded coverage of failure theory; and updated references.
Engineering education is currently on the verge of a major transformation. However, while the need has been much discussed and several proposals for change have been put forward, relatively little focus has been put on actual implementation of the proposed changes. This book examines a program that has a long history of experimentation in engineering education. Written by experts on the subject, it describes specific topics with each chapter focusing on a specific innovation that has been carried out and explaining the educational pedagogy the learning benefit, as well as the transferability of the approach.
