Mechanical engineering is an engineering discipline that involves the application of principles of physics for analysis, design, manufacturing and maintenance of mechanical systems. It requires a solid understanding of key concepts including mechanics, kinematics, thermodynamics and energy. Practitioners of mechanical engineering, known as mechanical engineers, use these principles and others in the design and analysis of automobiles, aircraft, heating & cooling systems, buildings and bridges, industrial equipment and machinery and more.

Mechanical Engineering is a discipline in the Science, Mathematics & Engineering Division division.
