Mechanical Engineering is one of the oldest engineering disciplines, having culminated from the industrial revolution of the 19th century. Traditionally concerned with harnessing and converting energy forms, mechanical engineers are inherently multi-disciplinary. For example, the design of a car engine combines the fields of chemistry, thermodynamics, heat transfer, fluid dynamics, electronic controls, dynamics and vibrations, materials science, and mechanical design. Although the mechanical engineer may specialize in one of these fields, a cursory knowledge of the each of these fields is necessary to interact with other engineers.
