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.

Fully up-to-date coverage of human factors engineering—plus online access to interactive demonstrations and exercises
Engineering accomplishments can be as spectacular as a moon landing or as mundane as an uneventful drive to the local grocery store. Their failures can be as devastating as a plane crash or a massive oil spill. Over the past decade, psychologists and engineers have made great strides in understanding how humans interact with complex engineered systems—human engineering.
Introduction to Humans in Engineered Systems provides historical context for the discipline and an overview of some of the real-world settings in which human engineering has been successfully applied, including aviation, medicine, computer science, and ground transportation. It presents findings on the nature and variety of human-engineering environments, human capabilities and limitations, and how these factors influence system performance. Important features include:
- Contents organized around the interaction of the human operator with the larger environment to guide the analysis of real-world situations
- A web-based archive of interactive demonstrations, exercises, and links to additional readings and tools applicable to a range of application domains
- Web content customizable for focus on particular areas of study or research

Mechanics of Flight is an ideal introduction to the basic principles of flight for students embarking on courses in aerospace engineering, student pilots, apprentices in the industry and anyone who is simply interested in aircraft and space flight. Written in a straightforward and jargon-free style, this popular classic text makes the fascinating topic of aircraft flight engaging and easy to understand. Starting with an overview of the relevant aspects of mechanics, the book goes on to cover topics such as air and airflow, aerofoils, thrust, level flight, gliding, landing, performance, manoeuvres, stability and control. Important aspects of these topics are illustrated by a description of a trial flight in a light aircraft. The book also deals with flight at transonic and supersonic speeds, and finally orbital and space flight.
