What is an Engineer?

A person whose job is to design, build or repair engines, machines, etc is called engineer.    In other words Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements. An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics and ingenuity to develop solutions to technical and practical problems. Engineers design materials, structures, machines, and systems considering the limitations imposed by practicality, safety, and cost. The word engineer is derived from the Latin root ingenium, meaning “ingenuity”. The work of engineers makes connections between scientific discoveries and applications that meet the needs of society. Engineers seek new principles and processes using mathematical and scientific concepts and experimental techniques. Engineers apply the results of research for useful purposes. The creative application of new knowledge results in a working model of a new electrical circuit, a chemical process, or an industrial machine. In designing a structure or product, the engineer selects methods, specifies materials, and determines sizes to meet technical requirements and meet performance specifications. The engineer is responsible for preparing the site, determining processes that will economically and safely achieve the desired quality, directing the placement of materials, and organizing personnel and equipment. Plant layout and equipment selection are the responsibility of the production engineer. , which selects the procedures and equipment, controls the machines, plants, and organizations that provide communications; prescribes procedures; and supervises personnel to achieve reliable and economical operation of complex equipment. Engineers analyze customer requirements, recommend units to economically meet needs, and solve related problems. Edith Clark. In 1918, Edith Clark became the first woman to earn an electrical engineering degree from the Massachusetts Institute of Technology. The first engineer known by name and accomplishment is Imhotep, who built the Step Pyramid at Haqqrah, Egypt, probably around 2550 BC.

Er. is the shorthand or short form of Engineer, Er. means Engineer.

What is Engineering?

The work that is done by an engineer is engineering. Engineering is the practice of using science, mathematics, and the engineering design process to solve technical problems, increase efficiency and productivity, and improve systems. Engineering is work involved in the design and construction of engines and machinery, or structures such as roads and bridges. Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, and maintenance of structures, machines, materials, equipment, systems, processes, and organizations.

Broadly, engineering can be divided into four main categories –

1 – Civil Engineer

2 – Electrical Engineer

3 – Mechanical Engineer

4 – Chemical Engineer
