Mechanical engineering is a very broad field of engineering that involves the application of physical principles for analysis, design, manufacturing, and maintenance of mechanical systems. The process of mechanical engineering can be as simple as the design of a wheel or as complex as the optimization of a turbocharged engine for speed. It can be as small as the cutting of a nano-sized gear or as large as the assembly of a supertanker used to carry oil around the world. It is a diversifying study of engineering, encompassing areas ranging from robotics machine to computational mechanics, composite materials and teratology.
Mechanical engineering continues to play a key role in developing, operating and manufacturing new machines, devices and processes to benefit mankind. Mechanical engineers apply their creative imaginations and professional skills to combine both theory and practice in a variety of situations. For this, they need an in-depth understanding of scientific principles and engineering processes. They also need to be able to develop solutions to real-life problems in the face of conflicting requirements. Mechanical engineers in the commercial world combine technical and management skills to retain the competitive advantage for their companies. Mechanical Engineering is a diverse profession that lies at the crossroads of all the engineering disciplines. 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.
