Mechanical engineering

Mechanical Engineering is an engineering discipline that involves the application of principles of physics for analysis, design, manufacturing, and maintenance of mechanical systems. It requires a solid understanding of key concepts including mechanics, kinematics, thermodynamics and energy. Mechanical engineers use these principles and others in the design and analysis of motor vehicles, aircraft, heating & cooling systems, watercraft, manufacturing plants, industrial equipment and machinery, medical devices and more.

Mechanical engineering could be found in many ancient and medieval societies throughout the globe. In ancient Greece, the works of Archimedes (287 BC–212 BC), and Heron of Alexandria (10–70 AD) deeply influenced mechanics in the Western tradition. In ancient China, there were also many notable figures, such as Zhang Heng (78–139 AD) and Ma Jun (200–265 AD). The medieval Chinese horologist and engineer Su Song (1020–1101 AD) incorporated an escapement mechanism into his astronomical clock tower two centuries before any escapement could be found in clocks of medieval Europe, as well as the world's first known endless power-transmitting chain drive.

During the early 19th century in Britain, the development of machine-tools led mechanical engineering to develop as a separate field within engineering, providing manufacturing machines and the engines to power them. The first British professional society of mechanical engineers was formed in 1847, making mechanical engineering the second-oldest branch of engineering behind civil, formed 30 years earlier. In the United States, the first mechanical engineering professional society was formed in 1880, making it the third oldest type of engineering behind civil (1852) and mining & metallurgical (1871). The first schools in the United States to offer an engineering education were the United States Military Academy in 1817, an institution now known as Norwich University in 1819, and Rensselaer Polytechnic Institute in 1825. Education in mechanical engineering has historically been based on a strong foundation in mathematics and science; this is followed by courses emphasizing the application of this knowledge and studies in the social sciences and humanities to give the engineer a broader education.
