(n) A field of engineering comprising a wide range of activities, including research, design, development, manufacturing, management, and control for engineering systems and their components. Mechanical engineers work in such fields as transportation, power generation, energy conversion, environmental control, aeronautics, marine science, and manufacturing.
Mechanical engineering is a professional 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.
