The broadest of all Engineering disciplines deals with design and production of tools, machines and all other mechanical equipment to be used in industries. The industry offers a wide choice of options extending across many interdisciplinary interdependent specialties. The work of a Mechanical Engineer can be extremely challenging and fulfilling, requiring IT, design and analytical skills together with an ability to work as a team.
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. They not only design and create new products, but also develop materials for them and ways of making them.
In a way, mechanical engineers are involved in creating the future. They are the driving force behind many of our technologies and industrial processes including innovative products like mobiles, PCs and DVD etc in our modern world. As their work involves production, transmission and use of mechanical power and heat, they have to analyse the different materials used for the machines and their tolerances, investigate the different energy sources and the power they generate and the design problems if any.
When designing and making a commercial product they have to take into account all the business and marketing aspects to make sure that the product is affordable. They share interests with many other engineers like Civil Engineers in structures and stress analysis; Mechanical Engineers are also responsible for maintenance and repair of the devices. Care has to be taken that the plants give maximum output and the machinery is properly maintained.
