2、any ancient and medieval societies throughout the globe. In ancient Greece, the works of Archimedes (287 BC212 BC), and Heron of Alexandria(1070 AD) deeply influenced mechanics in the Western tradition. In ancient China, there were also many notable figures, such as Zhang Heng(78139 AD) and Ma Jun (

The medieval Chinese horologist and engineer Su Song (10201101 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 worlds first known endless power-transmitting chain dr

Mechanical Engineering English 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 mecha

7、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.Mechanical Engineeri

The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. 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
