What Different Engineers Do For The World

, Author

Engineering plays a vital role in the growth, development, and technological advancement of a country and has major contributions in the economy as well as in enhancing the quality of living for citizens, so there is a direct linkage between the engineering competence and the county’s economic upsurge.


World Engineers Day is celebrated on March 2, and in different countries, it is celebrated on different dates, i.e. in India, it is on September 15, in Australia, it is celebrated on March 4, etc.


Applications of Engineering

  • It is the engineers who weave the technology and industrial infrastructure of a country. What do they do – Roads are not built without them, bridges do not get built in their absence; buildings cannot get constructed, machines do not exist. From small appliances to aeroplanes, nothing is ready until engineers design and review the product. Our everyday devices, phones, tablets, cars, without the engineer to meet safety and robust expectations, rapid advancement and developments of the twenty-first-century would have long spun off course. That is to say that engineering is the basis of sustainable progress and prosperity.
  • What future commodity hides in the front lines of potential resources, only the engineer can tell.
  • They can be found working in industrial plants,  in laboratories, on construction sites, in offices fretting over every little detail of a visionary’s design. In their absence, skyscrapers would crumble faster than you can say “engineer”; it would have been impossible to walk on the waves of the sea or in the deep, visions of mankind flying in the sky would remain a distant dream. Where would we be without computers? It’s only because of software engineering that society today can be so connected and entertained right from the comfort of our homes.


Specializations in Engineering

  • Mechanical engineering (ME) can be considered the mother of all engineering branches. Mechanical engineering applies physical principles and material science to the design, construction, and analysis of mechanical systems.
  • Electrical engineering

electrical engineer in sketch design processElectrical engineering (EE) involves the study and applications of electricity and electronics. Some computer engineering and software engineering consider subdisciplines of electrical engineering. In fact, the best electrical engineering internship opportunities will familiarise you across these different disciplines, and collaborating with engineers from these sub-fields. Electronic engineering, optical engineering, electrical engineering, control engineering, and telecommunications engineering are EE specialties.

  • Mechatronics

Mechatronics combines mechanical engineering and electrical engineering, often in the analysis of automated systems.

  • Biomedical engineering

Biomedical engineering characterizes one another by applying engineering principles to medical and biological problems and systems. This discipline is usually related to medical treatment, monitoring devices, and diagnostic equipment.

  • Nanoengineering

Nanoengineering is the application of engineering on extremely small or nanoscopic scales.

  • Nuclear engineering

Nuclear engineering has practical applications in nuclear processes, such as those used to produce and use nuclear power.

  • Structural Engineering

Structural engineering is concerned with the design and analysis of load-bearing structures and supports.

  • Chemical engineering

Chemical engineering (CE) has relevance to the chemistry of creating new substances or mediums and processes them to convert into useful commodities

  • Civil Engineering

Civil engineering (CE) is one of the oldest methods of engineering. The civil engineering discipline is concerned with the design, construction, analysis, and maintenance of structures, natural and man-made, including bridges, roads, dams, and buildings.

Computer Engineering

Integrates computer science with the development of computer engineering and electrical engineering to analyze circuits, microprocessors, and computers. A computer engineer is, while software engineers traditionally focus more on hardware, focusing on programming and software design.

  • Automobile engineering

This branch of vehicle engineering includes naval architecture, automotive engineering, and aerospace engineering. Its application is the design, manufacture, and functioning of vehicles.


There are many more engineering branches, always directed towards the development and making our lives easier and maintaining the esteem of the machine age. Many undergraduates start seeking degrees in mechanical, chemical, civil, or electrical engineering and develop expertise through available internship sources, employment, and modern education.
