History of mechanical engineering. Mechanical engineering is a discipline centered around the concept of using force multipliers, moving components, and machines. It utilizes knowledge of mathematics, physics, materials sciences, and engineering technologies. It is one of the oldest and broadest of the engineering disciplines.
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [ 1 ] It is one of the oldest and broadest of the engineering branches.
A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines.
The word "engine" itself is of even older origin, ultimately deriving from the Latin ingenium (c. 1250), meaning "innate quality, especially mental power, hence a clever invention." [2] Later, as the design of civilian structures such as bridges and buildings matured as a technical discipline, the term civil engineering [3] entered the lexicon ...
Mechanization. A water-powered mine hoist used for raising ore. This woodblock is from De re metallica by George Bauer (pen name Georgius Agricola, ca. 1555) an early mining textbook that contains numerous drawings and descriptions of mining equipment. Mechanization (or mechanisation) is the process of changing from working largely or ...
Newcomen's atmospheric steam engine. The first practical mechanical steam engine was introduced by Thomas Newcomen in 1712. Newcomen apparently conceived his machine independently of Savery, but as the latter had taken out a wide-ranging patent, Newcomen and his associates were obliged to come to an arrangement with him, marketing the engine until 1733 under a joint patent.

Mechanism (engineering) Schematic of the actuator mechanism for an aircraft landing gear. In engineering, a mechanism is a device that transforms input forces and movement into a desired set of output forces and movement. Mechanisms generally consist of moving components which may include Gears and gear trains; Belts and chain drives; cams and ...
A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment output displays. More complex examples could carry out multiplication and division—Friden used a ...
