brake
Science; General science
A machine element for applying a force to a moving surface to slow it down or bring it to rest in a controlled manner. In doing so, it converts the kinetic energy of motion into ...
spring (machines)
Science; General science
A machine element for storing energy as a function of displacement. The flywheel, in contrast, is a means for storing energy as a function of angular velocity. Force applied to a ...
antifriction bearing
Science; General science
A machine element that permits free motion between moving and fixed parts. Antifrictional bearings are essential to mechanized equipment; they hold or guide moving machine parts ...
gear
Science; General science
A machine element used to transmit motion between rotating shafts when the center distance of the shafts is not too large. Toothed gears provide a positive drive, maintaining ...
steam engine
Science; General science
A machine for converting the heat energy in steam to mechanical energy of a moving mechanism, for example, a shaft. The steam engine dominated the industrial revolution and made ...
steam turbine
Science; General science
A machine for generating mechanical power in rotary motion from the energy of steam at temperature and pressure above that of an available sink. By far the most widely used and ...
turbine
Science; General science
A machine for generating rotary mechanical power from the energy in a stream of fluid. The energy, originally in the form of head or pressure energy, is converted to velocity ...
