Abstract
1 min readA brake is a device used for slowing or controlling speed to a certain value under varying conditions, or for stopping a vehicle or other moving mechanism by the absorption or transfer of the energy of momentum, usually by means of friction. Brakes are used in cars or other vehicles where safe, fast, and smooth stopping is needed, or in elevators, escalators, hoists, and winches that must stop and hold a load after lifting it. Also, machine tools, conveyors, and other manufacturing equipment that must often be brought to a safe, quick stop employ brakes. This chapter examines the types of brakes in mechanical applications, covering the full design of several types of brake, along with examples and solved/unsolved problems. The chapter describes the force and stress analysis of brakes such as band brakes, external shoe drum brakes, and internal shoe drum brakes. This chapter can be used as teaching material for courses in machine design for mechanical and industrial engineering majors in colleges and universities, and can also be used as a reference for scientific and technical personnel engaged in scientific and engineering calculations.
