Mechanical engineering involves understanding core concepts in mechanics, kinematics, thermodynamics, materials science, and structural analysis to design and analyze machines, systems, and other mechanical devices. Mechanical engineers work across many industries to design manufacturing plants, industrial equipment, transport systems, medical devices, and more using computer-aided engineering and product lifecycle management. Some examples of mechanical engineering include bicycles, CD players, snowmobiles, robots, and nanotechnology, with new areas including biomechanics, MEMS, and composite materials. Mechanical engineers have career opportunities in sectors like automotive, manufacturing, aerospace, energy and utilities, and biomechanics.
