Mechanical Engineering is a profession that concerns itself with mechanical design, energy conversion, fuel and combustion technologies, heat transfer, materials, noise control and acoustics, manufacturing processes, rail transportation, automatic control, product safety and reliability, solar energy, and technological impacts to society. Mechanical engineers study the behavior of materials when forces are applied to them, such as the motion of solids, liquids, gasses, and heating and cooling of objects and machines. Using these basic building blocks, mechanical engineers design space vehicles, computers, power plants, intelligent machines and robots, automobiles, trains, airplanes, furnaces. and air-conditioners. Mechanical engineers work on jet engine design, submarines, hot air balloons, textiles and new materials, medical and hospital equipment, and refrigerators and other home appliances. Anything that is mechanical or must interact with another machine or human being is within the broad scope of mechanical engineering.(SOURCE: CMO-97-s-2017).
