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.
The development of machine tools and the system of interchangeable parts was the basis for the rise of the US as the world's leading industrial nation in the late 19th century. Oliver Evans invented an automated flour mill in the mid-1780s that used control mechanisms and conveyors so that no labour was needed from the time grain was loaded ...
The ziggurats of Mesopotamia, the pyramids and Pharos of Alexandria in ancient Egypt, cities of the Indus Valley civilization, the Acropolis and Parthenon in ancient Greece, the aqueducts, Via Appia and Colosseum in the Roman Empire, Teotihuacán, the cities and pyramids of the Mayan, Inca and Aztec Empires, and the Great Wall of China, among many others, stand as a testament to the ingenuity ...
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 development of the stationary steam engine was a very important early element of the Industrial Revolution. However, it should be remembered that for most of the period of the Industrial Revolution, the majority of industries still relied on wind and water power as well as horse and man-power for driving small machines.
The history of numerical control (NC) began when the automation of machine tools first incorporated concepts of abstractly programmable logic, and it continues today with the ongoing evolution of computer numerical control (CNC) technology. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with ...
History of the steam engine. The 1698 Savery Steam Pump - the first commercially successful steam powered device, built by Thomas Savery. [1] The first recorded rudimentary steam engine was the aeolipile mentioned by Vitruvius between 30 and 15 BC and, described by Heron of Alexandria in 1st-century Roman Egypt. [2]
One of his studies on Newtonian mechanics led him to create a shearing machine in 1910 that converted curvilineal motion into straight line movement. The device is the basis of modern mechanical shears. [23] In the 1910s and 1920s, Harry Perrigo of Kansas City, Missouri, a graduate of MIT, claimed development of a free energy device. [24]
