Mechanical engineering is a very broad field that involves the application of physical principles for analysis, design, manufacturing, and maintenance of mechanical systems. It is made up of a number of subdisciplines concerned with the mechanics, kinematics (movement), and energy of physical objects. Practitioners of mechanical engineering, known as mechanical engineers, use principles such as heat, force, and the conservation of mass and energy in contributing to the design of vehicles and aircraft, heating & cooling systems, buildings and bridges, industrial equipment and machinery, and much more.
