Mechanical engineering is one of the broadest engineering disciplines, and mechanical engineers perform a wide range of tasks. They research, design, develop, manufacture, and test engines, machines, tools, and other mechanical devices. They may work in manufacturing, technical sales, agricultural production, or maintenance. Mechanical engineers often design tools used by other engineers.
Civil engineers are responsible for designing and supervising the construction of roads, buildings, airports, tunnels, dams, bridges, and water supply and sewage systems. They must be mindful of government regulations and potential environmental hazards. Civil engineers encompass many specialties, including structural design, water resources, construction, transportation, and geotechnical engineering.
Electrical engineers develop, test, and supervise the manufacturing of electrical equipment including electric motors, machinery controls, lighting, radar, navigation systems, and more. Many electrical engineers design the electrical systems of aircraft and automobiles. Areas of specialization for electrical engineers include power systems engineering and electrical equipment manufacturing.
