Mechanical Engineering is the scientific discipline applied to make a product from a concept or an idea and bring it to the marketplace, by developing the functional, construction and energy-related aspects of any products, processes and systems in industry and in the advanced tertiary sector. Mechanical engineering is probably the broadest and most diverse of of the engineering disciplines with one unique skill, among several others: the ability to analyze and design objects and systems with motion.
Mechanical engineering play a central role in such industries as automotive (from the car chassis to its every subsystem—engine, transmission, sensors); aerospace (airplanes, aircraft engines, control systems for airplanes and spacecraft); biotechnology (implants, prosthetic devices, fluidic systems for pharmaceutical industries); computers and electronics (disk drives, printers, cooling systems, semiconductor tools); electro-mechanical systems, (sensors, actuators, power generation); energy conversion & storage (gas turbines, wind turbines, solar energy, fuel cells, batteries); environmental control (HVAC, air-conditioning, refrigeration, compressors); automation (robots, data and image acquisition, recognition, process monitoring & control); manufacturing (prototyping, machining & machine tools, welding, pressing, bending, molding & fabrication). Dealing with materials, solid and fluid mechanics & dynamics, thermodynamics, heat transfer, modeling & simulating, design & manufacturing, control & testing, of any mechanical systems.
