This branch of engineering is concerned with the design, production, and operation of machinery ranging from simple to highly complex machinery and in some cases entire facilities and plants. Those keen on entering this field will get the opportunity to work in industries such as computing, construction, automotive, biotechnology, and aerospace, medical among many more that require the development of things such as robots, fuel cells, engine parts to wind or gas turbines, and more. Mechanical engineering came to the fore during the Industrial Revolution that took place in Europe during the 18th century. Today mechanical engineering is an extremely well-paid career.
