Mechanical engineering is a discipline of engineering that applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines. The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided engineering, 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 Engineers touch almost every aspect of technology. They create machines, products and technological systems that benefit society.

Mechanical engineering projects can range from designing heart valves and artificial limbs, clockwork radios and dentists’ drills, building racing cars, jet engines, space modules, solar heaters and wind mills. Mechanical Engineering is a large and diversified field. All engineers have a common interest in heat and motion. Mechanical engineers use the principles of mathematics, material science, physics and economics to design, to manufacture and to maintain mechanical equipments. Our household appliances, chimneys, cars, ships and airplanes have been designed, tested and manufactured by mechanical engineers. Wherever there are machines, there is a necessity of Mechanical Engineers. Wherever Mechanical Engineers work, they are engaged in one or more of eight different fields: Research, Development, Design, Testing, Manufacturing, Operations, Maintenance, and Marketing & Sales Administration. Mechanical Engineering is specifically concerned with anything that has movable parts. As a result, there are job opportunities for Mechanical Engineers in all fields of work such as transport, health, defense, manufacturing, power station, energy management, entertainment, finance, publishing, building, design and research, to name a few.
