The field has continually evolved to incorporate advancements today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. In the 19th century, developments in physics led to the development of mechanical engineering science. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century however, its development can be traced back several thousand years around the world. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. Mechanical engineering requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, design, structural analysis, and electricity. It is one of the oldest and broadest of the engineering branches. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. Mechanical engineering is the study of physical machines that may involve force and movement.
