In China, Zhang Heng (78–139 AD) improved a water clock and invented a seismometer, and Ma Jun (200–265 AD) invented a chariot with differential gears. 10–70 AD) created the first steam-powered device ( Aeolipile). In ancient Greece, the works of Archimedes (287–212 BC) influenced mechanics in the Western tradition.
The earliest practical water-powered machines, the water wheel and watermill, first appeared in the Persian Empire, in what are now Iraq and Iran, by the early 4th century BC. Kushite sundials applied mathematics in the form of advanced trigonometry. Bloomeries and blast furnaces were developed during the seventh century BC in Meroe. Reservoirs in the form of Hafirs were developed in Kush to store water and boost irrigation. It relied on animal power reducing the tow on the requirement of human energy. The Sakia was developed in the Kingdom of Kush during the 4th century BC. The earliest evidence of pulleys date back to Mesopotamia in the early 2nd millennium BC. The lever was also used in the shadoof water-lifting device, the first crane machine, which appeared in Mesopotamia circa 3000 BC. The lever mechanism first appeared around 5,000 years ago in the Near East, where it was used in a simple balance scale, and to move large objects in ancient Egyptian technology.
The wheel, along with the wheel and axle mechanism, was invented in Mesopotamia (modern Iraq) during the 5th millennium BC. The wedge and the inclined plane (ramp) were known since prehistoric times. The six classic simple machines were known in the ancient Near East. The application of mechanical engineering can be seen in the archives of various ancient and medieval societies. Main article: History of mechanical engineering Mechanical engineers may also work in the field of biomedical engineering, specifically with biomechanics, transport phenomena, biomechatronics, bionanotechnology, and modelling of biological systems. It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, structural engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts. The field has continually evolved to incorporate advancements today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. In the 19th century, developments in physics led to the development of mechanical engineering science. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century however, its development can be traced back several thousand years around the world. It is the branch of engineering that involves the design, production, and operation of machinery. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. It is one of the oldest and broadest of the engineering branches. Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. He is the author of more than 100 books in engineering and related fields.Technology, science, exploration, military Hicks holds a bachelor’s degree in Mechanical Engineering from Cooper Union School of Engineering in New York. He has worked in plant design and operation in a variety of industries, taught at several engineering schools, and lectured both in the United States and abroad. Hicks, P.E., is a consulting engineer and a successful engineering book author.
