Traditionally, the main branches of engineering are chemical engineering, civil engineering, electrical engineering, biological engineering, and mechanical engineering, but there are many other areas of specialization.Civil engineering is one of the oldest forms of engineering.
Civil engineering pertains to the discipline pertaining to the design, construction, analysis, and maintenance of structures, both natural and man-made, including bridge, roads, dams, and buildings.
Some consider computer engineering and software engineering to be sub-disciplines of electrical engineering.
Mechanical engineers design, manufacture, and operate systems that extend our physical abilities.
This includes designing an aircraft, planning a building's ventilation system and improving a car's fuel economy.
Mechanical engineering also saves lives through bioengineering technologies.
