Mechanical engineers design power-producing machines, such as electric generators, internal combustion engines, and steam and gas turbines, as well as power-using machines, such as refrigeration and air-conditioning systems. Mechanical engineers design other machines inside buildings, such as elevators and escalators.

What is mechanical design? Often referred to as engineering design or machine design, mechanical design is the process of designing components, parts, products, and systems that are inherently mechanical in nature. Any type of machinery or any product that has complex parts requires some form of mechanical design.

Mechanical engineering deals with the design, development, installation, operation and maintenance of anything that has moving parts. Because of this, you'll find relevant opportunities in a range of sectors, including: aerospace engineering.
