Mechanical engineering is the discipline that applies the principles of engineering, physics and materials science for the design, analysis, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the design, production, and operation of machinery and tools. It is one of the oldest and broadest of the engineering disciplines. Mechanical engineers design and build engines, power plants. 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, weapons, and others, 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, metallurgical engineering, civil engineering, electrical engineering, petroleum engineering, manufacturing engineering, chemical engineering, and other engineering disciplines to varying amounts. Mechanical engineers may also work in the field of Bio medical engineering, specifically with bio mechanics, transport phenomena, biomechatronics, bio nanotechnology and modeling of biological systems, like soft tissue mechanics. Mechanical Engineering includes design, manufacture, installation and operation of engines, machines, robotics, heating & cooling systems and manufacturing processes. In this profession, you will be responsible for designing and developing machines right from bicycles to supersonic fighter jets and toasters which can be extremely challenging and fulfilling, requiring analytical skills together with an ability to work in a team. You must love machines and be comfortable working with tools! Graduates can work in the automotive, aerospace, chemical, computer, communication, paper, power generation and almost all manufacturing industries. Mechanical engineers also work in maintenance and service profiles in all industries. Also they can choose teaching profession in universities and colleges.
