Mechanical Engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools. It is one of the oldest and broadest engineering disciplines.
The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided engineering and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, and others.
Mechanical engineering emerged as a field during the industrial revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. Mechanical engineering science emerged in the 19th century as a result of developments in the field of physics. The field has continually evolved to incorporate advancements in technology, and mechanical engineers today are pursuing developments in such fields as composites, mechatronics, and nanotechnology. Mechanical engineering overlaps with aerospace engineering,railway engineering, building services engineering, metallurgical engineering, marine engineering, civil engineering, electrical engineering, petroleum engineering, manufacturing engineering, and chemical engineering to varying amounts. Mechanical engineers also work in the field of Biomedical engineering, specifically with biomechanics, transport phenomena, biomechatronics, bionanotechnology and modeling of biological systems, like soft tissue mechanics.
There is a wide scope for Mechanical engineering worldwide. Mechanical engineers are the second highest employed engineers among all others with only 7% unemployed whereas any normal engineering stream would have around 15% unemployed engineers worldwide.we have the automobile industry,oil and gas production companies,aeronautical field,cement industries,design sector,chemical industries,heavy machinery sector,information technology,defense and above all the booming construction field always waiting on for mechanical engineers with lucrative pays and packages.
hanical Engineering finds application in all fields of technology. It is one of the primitive branches of Engineering which have remained always in demand and continue to be in the future. This is why Mechanical trade is called as an Evergreen trade (branch). Mechanical engineers have always been needed as an essential staff personnel in various industries of both public and private sector. Their work criteria changes according to the type and domain of the company they are working with.As the Industrial sector has drastically risen in pace, the need for more mechanical engineers has increased exponentially. Every manufacturing and production industry needs mechanical engineers to carry out jobs efficiently and flawlessly for their companies.
As the Working criteria of a mechanical Engineer changes according to the type and domain of the company they are working with and field of specialisation we can broadly say that a mechanical Engineer works how to Design and control a system that goes into the process of manufacturing the machinery and product. He tests new systems for feasibility and efficiency and carries out Quality management and improvement process.
