Mechanical is a discipline of engineering that applies the Principles of Physics and materials science for the analysis, design, manufacturing, and maintenance of mechanical systems. It is a 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, etc.
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 Mechanical engineering science emerged in the 19th century as a result of developments in the field of Physics. The field has continually evolved to incorporate advancements in technology and mechanical engineers today are pursuing developments in such fields as composites, Mechatronics, and Nanotechnology. Mechanical Engineering overlaps Aerospace Engineering, Building Services Engineering, Metallurgical Engineering, Marine Engineering, Civil Engineering, Electrical Engineering, Petroleum Engineering, Manufacturing Engineering, and Chemical Engineering, etc.
Mechanical Engineers also work in the field of Biomedical Engineering, specifically with Bio-mechanic, transport phenomena, and modeling of biological systems, like soft tissue mechanics.
