TYPES OF ENGINEERING

The main Branches of Engineering are categorized:

Aerospace Engineering: Aerospace engineers design, develop, test, and product aircraft, spacecraft, aerospace equipment, satellites and missiles.

Chemical Engineering: Chemical engineer translate raw materials into usable commodities. They apply the principle of chemistry consider solving problem in production or using of chemical and biochemical. Chemical engineers apply principles of physics, mathematics, and mechanical and electrical engineering chemistry.

Civil Engineering: Civil Engineers design and construct roads, buildings, airports, bridges, water supply and sewage system. They must consider many factors in the design process, from the construction costs and expected living conditions and potential environmental hazards such as earthquakes and hurricanes.

Electrical Engineering: Electrical engineers design, develop, test and control the manufacture of electrical equipment. This engineering Electrical engineering is the application of the laws of physics governing electricity, magnetism, and light to develop new technologies to help humankind. If it involves electricity, it involves electrical engineering.

Mechanical Engineering: Mechanical Engineers design, develop and test mechanical devices such as engines, power trains, kinematics chains and vibration isolation equipment. Mechanical engineers design tools that other engineers need for their work.

The other types of engineering are:

Agricultural engineers: Design farm equipment, animal shelters, crop systems, and product processing systems.
computer engineers: Design, construct, and maintain electronic systems, but additional trainining in the areas of sortware design and hardware-sortware integration
Geological engineers: Solves earth related technical problems while at the same time protecting the environment.
Materials engineers: Study metals, ceramics, plastics, and composites to design materials for applications that may involve transportation, communication or power production.
Nuclear engineers: Work with nuclear reactors, fusion and radiation applications.
Industrial Engineering: Industrial engineers consider the most effective and efficient ways to use the basic factors of making a product on providing a service. Duty of industrial engineering is to provide productivity, efficiency, effectiveness and so this engineers applies the scientific management methods. Industrial engineering differs from the other engineering because that engineer manages whole system with other engineers in order to do duty. Moreover, unlike other engineering, human factor is important for industrial engineering. Consequently, industrial engineering must be in whole fields of industry to conduct people, machines, materials, information and energy.
