-Engineering is often characterized as having four main branches: chemical, civil, electrical and mechanical engineering.
i)Chemical engineering – The application of physics, chemistry, biology, and engineering principles in order to carry out chemical processes on a commercial scale, such as petroleum refining, microfabrication, fermentation, and biomolecule production.
ii)Civil engineering – The design and construction of public and private works, such as infrastructure (airports, roads, railways, water supply and treatment etc.), bridges, dams, and buildings.
iii)Electrical engineering – The design and study of various electrical and electronic systems, such as electrical circuits, generators, motors, electromagnetic/ electromechanical devices, electronic devices, electronic circuits, optical fibers, optoelectronic devices, telecommunications, computer systems, instrumentation, controls, and electronics.
iv)Mechanical engineering – The design of physical or mechanical systems, such as power and energy systems, aerospace/aircraft products, weapon systems, transportation products, engines, compressors, powertrains, kinematic chains, vacuum technology, and vibration isolation equipment.
v)Beyond these four, sources vary on other main branches. Historically, naval engineering and mining engineering were major branches.
vi)Modern fields sometimes included as major branches are manufacturing engineering, acoustical engineering, corrosion engineering, Instrumentation and control, aerospace, automotive, computer, electronic, petroleum, systems, audio, software, architectural, agricultural, biosystems, biomedical, geological, textile, industrial, materials, and nuclear engineering.
