Mechanical engineering, one of the broadest engineering disciplines, applies the principles of engineering, physics, and materials science to the design, production, and operation of machinery.

Mechanical engineers use the core engineering principles along with tools like computer-aided design, to deal with anything that moves. These engineers design and analyze systems such as manufacturing plants, industrial equipment and machinery, heating and cooling systems, aircraft, automotive, robotics, and medical devices. Mechanical engineering designs and manufactures everything from small individual parts and devices to large systems.
