Conveniently gathering formulas, analytical methods, and graphs for the design and selection of a wide variety of brakes and clutches in the automotive, aircraft, farming, and manufacturing industries, Clutches and Brakes: Design and Selection, Second Edition simplifies calculations, acquaints engineers with an expansive range of application, and assists in the selection of parameters for specific design challenges.

Contains an abundance of examples, 550 display equations, and more than 200 figures for clear presentation of various design strategies

Thoroughly revised throughout, the second edition offers…
- Additional chapters on friction drives and fluid clutches and retarders

- An extended discussion on cone brakes and clutches

- A simpler formulation of the torque from a centrifugal clutch

- Updated sections on automatic braking systems

- An analysis of variable-speed friction drives with clutch capability

- Analytical and computer-assisted design techniques
