Engineering is the discipline, art, and profession of acquiring and applying scientific, mathematical, economic, social, and practical knowledge to design and build structures, machines, devices, systems, materials and processes that safely realize improvements to the lives of people.
Types of Engineering:
The primary types of engineering are chemical, civil, electrical, industrial, and mechanical.
Chemical engineering handles with the design, construction, and operation of plants and machinery for making such products as acids, dyes, drugs, plastics, and synthetic rubber by adapting the chemical reactions discovered by the laboratory chemist to large-scale production.
Civil engineering deals with the planning, designing, construction, and maintenance of structures and altering geography to suit human needs.
Electrical engineering consists of all aspects of electricity from power engineering, the development of the devices for the generation and transmission of electrical power, to electronics. Electronics is a branch of electrical engineering that deals with devices that use electricity for control of processes.
Industrial engineering is concerned with efficient production. The industrial engineer designs which includes plant layout, analysis and planning of workers' jobs, economical handling of raw materials, their flow through the production process.
Mechanical engineering is always concerned with the design, construction, and operation of power plants, engines, and machines. It deals mostly with things that move and a common way of dividing mechanical engineering is into heat utilization and machine design.
Aeronautical engineering is implemented in the designing of aircraft and missiles and in directing the technical phases of their manufacture and operation.
The other branches of engineering are agricultural engineering, engineering physics, geological engineering, naval architecture and marine engineering, and nuclear engineering.
Another way of dividing engineering is by function. Among the top functional divisions are design, operation, management, development, and construction; development engineering is concerned with converting an idea into a practical product.
