Mechanical engineers are concerned with the production, transmission and use of power.
They design and develop systems which produce power, such as steam and gas turbines, internal combustion engines, nuclear reactors, jet engines, and rocket motors. They also design, develop, and manufacture devices which consume power in order to accomplish some useful result, such as refrigeration and air conditioning equipment, machine tools, rolling mills, and elevators, to name a few. The environmental impact of these systems forms an integral part of their analysis and design. Mechanical engineers must cope with stringent standards of air and water quality, noise abatement and thermal pollution. Graduates find employment in a number of areas, including private industry, govern-ment, consulting firms and education.
