B. Tech – Mechanical Engineering


Mechanical engineering is the second largest and one of the oldest disciplines; broadest of all engineering disciplines. It deals with design and production of tools, machines and all other mechanical equipment used in any industry.

Mechanical engineering is concerned with all types of machinery in industries and all aspects of their mechanism and functioning, the design, development, construction, production, installation, operation and maintenance; such as large steam and gas turbines, components of thermal power stations, internal combustion engines, jet engines, machine tools, air conditioning and heating machines, refrigerators etc to name a few.



History of Mechanical Engineering


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. In the 19th century, developments in physics led to the development of mechanical engineering science. The field has continually evolved to incorporate advancements; today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts. Mechanical engineers may also work in the field of biomedical engineering, specifically with biomechanics, transport phenomena, biomechatronics, bionanotechnology, and modeling of biological systems.



Functionality area of Mechanical Engineering


Main functional areas comes under mechanical engineer are research, design, develop, build, and test mechanical and thermal devices, including tools, engines and machines.Mechanical engineers typically do the following:


  • Analyze problems to see how mechanical and thermal devices might help to solve the problem.
  • Develop and test various type of prototype which they design.
  • They consider various type of manufacturing process for developing the desired product.
  • They also design power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines as well as power-using machines, such as refrigeration and air-conditioning systems.
  • Like other engineers, mechanical engineers use computers to help create and analyze designs, run simulations and test how a machine is likely to work.
  • Mechanical engineers apply the principles of mechanics and energy to the design of machines and devices. All our household appliances, ventilation systems, bikes, cars, ships and airplanes have been designed, manufactured and tested by Mechanical Engineers.
  • Mechanical Engineers developed different type Robots for Industrial or Commercial usage.
  • Mechanical Engineers uses CAD/CAM (Computer Aided Design/ Manufacturing) systems to design & manufacture the products and design the mechanical and thermal devices with help of various design software.
