Introduction

Mechanical Engineering is one of the oldest branches of engineering and is also referred as the ‘MOTHER’ of all Engineering branches. Almost all inventions during the ancient period and a vast majority in the modern era are direct contributions of one or the other application of mechanics. Mechanical engineers have to deal with concepts such as mechanics, thermodynamics, robotics, kinematics, and many others, which are applied in the process of designing and developing different types of motor vehicles, aircraft and aerospace parts, a vast industrial machinery, various engines, power plant equipment, army weapons, tanks and other war equipment, ship-building, heating-ventilation and air conditioning (HVAC) systems and other simple and complex machinery. Mechanical engineers not only design new mechanical systems but they are also responsible for testing, maintaining and manufacturing them. Mechanical Engineers are responsible for making products from tiny needle to the spacecraft. Nowadays the scope of Mechanical Engineering is expanding beyond its traditional boundaries as now they are focusing their attention towards new areas of research such as nanotechnology, development of composite materials, biomedical applications, environmental conservation, etc. Every industry requires a Mechanical Engineer for their production irrespective of their products. All in all, Mechanical Engineering offers a wide bouquet of job options to students who are looking for a stable and stimulating career. So we can say Mechanical Engineering is not an option but it is the ‘existence for the mankind’.
