Steam Engine

A steam engine is a device that converts heat energy into mechanical work. To achieve high efficiency, the steam used in the engine must operate within a wide temperature range, allowing effective expansion. The steam engine typically consists of a piston and a cylinder, where pressurized steam is introduced through a valve mechanism. As the steam expands, it pushes the piston, which is connected to a crank on a flywheel, generating rotary motion. In a simple steam engine, the steam expands in only one cylinder. However, more advanced engines may use two or more cylinders, allowing for greater steam expansion and thus increased efficiency. The first commercial steam engine was introduced in 1698, although it was relatively inefficient and required improvements over time. The steam engine became one of the pivotal inventions of the Industrial Revolution.
