What began mechanical engineering
Mechanical engineering history
Mechanical engineering - also known as mechanical engineering - deals with the design and production of machines and machine components. With the industrial revolution (second half of the 18th century and increasingly in the 19th century, starting from England), mechanical engineering began to establish itself in its current form - both as a branch of industry and as an engineering discipline and subject of study.
The mechanical engineering industry is a mainstay of the German economy and is strongly oriented towards the export business. As a branch of industry, mechanical engineering emerged from the metalworking trade - which was previously dominated by blacksmiths and locksmiths. Everything revolves around the manufacture and sale of capital goods that are needed to create and process physical products.
In the pre-industrial period there were already around 700 BC. First mechanical engineering works - for example pumping stations in Assyria or around 550 BC First machine tools, such as an antique lathe. Around 340 BC Aristotle defined levers and screws and referred to them as machines and as early as 200 BC. Heron of Alexandria designed the first heat engine.
The beginning of the modern mechanical engineering industry in Germany goes back, among other things, to the locksmith and entrepreneur Johann von Zimmermann (1820-1901). He is considered to be the founder of machine tool construction, as he built the first factory for the construction of machine tools in Chemnitz in 1848. After that, Chemnitz stayed here until the end of the second worldwar plays an exposed role. That was true both for Germany and for the European continent.
Even today, the mechanical engineering sector is characterized by medium-sized companies - over 90 percent of the companies have fewer than 500 employees. In 2011, the German mechanical engineering industry - according to a graphic from "Welt" - employed 931,000 people. Sales in the same year amounted to 201 billion euros, of which 142.2 billion euros came from the export business. Mechanical engineers, but also technicians and skilled workers, work in the mechanical engineering sector.
As a subject of study, mechanical engineering as an applied science is one of the oldest engineering sciences and is based on both scientific knowledge and physical laws. The aim is to derive new and improve existing technologies, technical products, processes and services.
The training of engineers as well as the research knowledge in parts of mechanical engineering were
and are important for social progress, which has been very technical since the industrial revolution. In the middle of the 19th century, new universities and university branches emerged in many cities, which integrated the new area of mechanical engineering into their curriculum. As a modern subject, mechanical engineering refers to classical physics, especially classical mechanics.
The basic subjects that are taught as part of the mechanical engineering course are on the one hand natural science subjects, such as mathematics and physics, but also chemistry or technical thermodynamics and technical mechanics as well as electrical engineering and flow and fluid mechanics, as well as the technical subjects such as computer science, materials science and materials science, production and manufacturing technology, construction technology, but also machine elements as well as measurement and control technology.
