Engineering is the implementation of Mathematics, science, social, economic and practical knowledge. Engineering is a very broad stream and incorporates a lot of arenas of it and focuses more on applied science, its types and technology.
Engineering is not a new term, it has an existence since ancient times as human inventions were started and these inventions were merged with the modern definition of engineering. Initially engineering was divided into Civil, Mechanical, Electrical and Chemical with their further subdivisions. This in present day has 6 branches, Management and Geotechnical to be added by others and hundreds of subdivisions under each of it. Engineering involves scientific studies that enable an engineer to invent, design or build things that eases and solves problems to attain practical goals. The modern world would not exist as we are all surrounded by the work done by engineers in their respective branches, which we call as "Technology".
Few Branches Of Engineering
Engineering is wide spread area of study that includes many branches and sub branches of studies. Below mentioned are types of engineering, students generally consider while applying for Undergrad and Grad courses.
Civil engineering is an oldest stream of engineering that deals with infrastructures and constructions. The primary aim of any university to provide a civil engineering program is to prepare the students with social responsibility, technical knowledge and lifelong learning skills. Civil engineering demands implications and promotes environmental and public safety. Assignments in civil engineering demands extensive studies and research with practical work on structural analysis and designs in CAD (computer aided design) like AutoCAD; numerical analysis in Mat lab, Mathematical, Mathcad etc. and other simulations and FEA.
It is related to the concepts of chemistry and involves the design and maintenance chemical processes for large scale manufacture. It is the evaluation and preparation of changing substances in a huge amount of progress and change of human arena. Such progress and changes are important for the field and is the baseline for growth in the following sectors like electronics, pharmaceutical, and chemical and petroleum. Chemical engineering is dissimilar from chemistry majorly in the specification of scales. The term large is a bit random as considered for commercial consumption.
Mechanical Engineering is a vast and a huge stream that obtains a need to design and manufacture of small parts and devices. The role of a mechanical engineer is to take a product from an idea to the marketplace. In order to accomplish this, a broad range of skills is needed. Mechanical Engineering involves the design, development, management of machines, thermodynamics, thermal energy, robotic devices, heat transfer, manufacturing and process plants to name a few. Through knowledge of softwares like Solidworks, CATIA, Pro E, ANSYS, Abacus is attained during the course.
Electrical engineering is a pioneer branch and a new stream in engineering. It is the arm of engineering that faces the technologies of electricity, electrical engineers that need to keep in mind the wide components and etc. This sort of study deals with electricity and power generation and transmission. Moreover, it includes the study of transformers, motors, generators and every other electrical machine.
Nuclear engineering is the field of engineering that handles the applications of nuclear and radiation procedures. This field of engineering is based upon the basic concepts of mathematics and physics that explain transportation of gamma rays and neutrons and the explanation of nuclear interactions. One of the most important applications of nuclear engineering is the nuclear reactors that are used to generate electricity.
Amalgamation of engineering and medicine is biomedical engineering and it focuses on the application of engineering principles to design instruments for medicine, health care diagnostics, and treatment. Biomedical engineering consists of a lot of research work and development having a broad selection of subfields. Some of the important applications include various therapeutic and diagnostic medical devices, pharmaceutical drugs, therapeutic biological and regenerative tissue growth.
Aerospace engineering is related to the development of spacecraft and aircraft. It is majorly divided into two sub-branches, namely: aeronautical and astronautical engineering. Aeronautical engineering was the term that was originally used in place of Aerospace engineering. It includes the technology that helps in operating and design of an aircraft. Aerospace engineering, particularly the astronautics branch, is often referred to as "rocket science".
Geotechnical engineering is a sub field of civil engineering, which studies the process of analyzing, building and ways to retain structures. The work of a Geotechnical engineer is to design and build structures. Geotechnical engineering is a multidisciplinary field that offers research and training possibilities to students studying physics, civil engineering, architectural engineering, marine engineering and other engineering disciplines concerned with the construction.
Computer engineering is a much wider field because it comprises of the knowledge of hardware, software, networking and programming. It is a broad spectrum that defines the various methodologies of computer systems and builds network architectures. In this discipline, students get knowledge on the design of integrated hardware to provide the solution of technical problems. Apart from embedded system, it is involved in other hardware computing activities like microprocessors, microcontrollers, personal computers, supercomputers, circuit designing among few.
Thermal Engineering is a study of heat energy and its transfer between different mediums. A thermal engineer is always a design expert for converting energy generated from various sources of power into mechanical, chemical or electrical energy. It draws on the science of thermodynamics, fluids, heat transfer, the most common example being the AC (air conditioner), boiler, combustion engine, etc.
Engineering carves a lot of hard work and proper concentration from a student. Be it any stream, you have to pay proper attention in a university lecture as well as the assignments, but somewhere it is difficult to understand the right way of doing the given assignment. You often try to make a balance between their university life and family/friends, but always end in despair. Studying hard and managing all assignments are a task and you end up in procrastination. Assignments require a good research and understanding of the topic and the softwares required to accomplish the task in the assignments. Handling softwares, calculations, numerical, analysis are another issue that you always face.
