Turbine - Steam turbines | Britannica

Turbine - Turbine - Steam turbines: A steam turbine consists of a rotor resting on bearings and enclosed in a cylindrical casing. The rotor is turned by steam impinging against attached vanes or blades on which it exerts a force in the tangential direction. Thus a steam turbine could be viewed as a complex series of windmill-like arrangements, all assembled on the same shaft.

Steam engine - Wikipedia

A steam engine is a heat engine that performs mechanical work using steam as its working fluid.The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work.The term "steam engine" is generally applied only to reciprocating engines as just
