Mechanical engineering is a broad field that is a subset of general engineering which involves the application of the principles of physics for the analysis, design, manufacturing and maintenance of mechanical systems. An engineer uses science and mathematical principles for solving the technical problems. This branch is made up of many sub disciplines that are concerned with the mechanics, kinematics and energy of physical objects.

This is one of the oldest and broadest engineering disciplines. The practitioners of mechanical engineering are also known as a mechanical engineer. A mechanical engineer plays a significant role in several fields such as automated manufacturing, transportation, environmental control, transportation, computer fields, fossil fuel, nuclear power and many more. These engineers are also concerned with imagining and implementing programs and devices that may improve our world and our movement in it.  A mechanical engineer is a specialized engineer who works with mechanical devices for e.g. elevators, refrigeration, robots, electric generators etc.

In the sector of agriculture, a mechanical engineer plays an important role by establishing service centers for maintaining the tractors, oil engines, electric motors, pump sets and other agricultural equipments. He can work in manufacturing firms as well as can find work in administrative and managerial positions in government departments or public sector industries. An individual can also start his career as technical sales or marketing engineers or independent consultants. The big demand of mechanical engineers is in the different areas such as steel, cement, constructions, infrastructure (maintenance) and process industries, Nuclear power plants, power plants and many more.

To sum up, we can say that Mechanical engineering is one of the most demanding engineering branch that brings lots of career opportunities for the people. After pursuing the engineering in mechanical, an individual can make his bright future in this field.
