Mechanical engineering is one of the broadest and oldest branches of engineering. Mechanical engineers are involved with the design, analysis, testing, manufacturing, control, operation and maintenance of mechanical system that is any system that has a moving part. Mechanical system can vary greatly in complexity and magnitude, from the valve in an artificial heart to a car engine to a mammoth nuclear plant.it deals with all aspects of the conversion of thermal energy into useful work and the machines that make this possible.
The scope of mechanical engineering is so wide and its service, so universally needed as a basic part of all kinds of engineering work that the mechanical engineer is in demand in all industries. Mechanical engineers are required in the field of power generation, where they deal with steam, diesel, or other internal combustion engines and with hydraulic or gas turbines, in the field of heating, ventilation and refrigeration, material handling equipment, automobiles, locomotives, marine vessels furnaces, boilers, pressure vessels, heat exchangers motors, generators and machine tools. They are employed in industries whose function is concerned with manufacturing, steel production, mining, transportation, communication, oil refining, chemical manufacture, paper, sugar, textiles, aerospace, nuclear energy, natural gas production and transmission and construction.

HOW TO BECOME A MECHANICAL ENGINEER
Traditionally, mechanical engineers have to deal with concepts such as machines
Thermodynamics, robotics, kinematics, structural analysis, fluid mechanics, design, system analysis, control analysis, vibration and machine design. These concept are applied in the process of designing state of the art manufacturing unit, different types of motor vehicles, aircraft and aerospace parts and a vast assortment of industrial machinery.
STEP BY STEP
Passing SSCE with a minimum of 5 credits in English, Mathematics’, Physics, Chemistry and any other science or technical course is the first step to becoming a mechanical Engineer. To be eligible for a graduate program (HND, B.TECH) in a college, you should obtain these credits and after that you can sit for the various entrance examination such as:
These graduate programs may be in form of a program, the student can go for the two years master program (M.Tech) in the universities
IS IT THE RIGHT CAREER FOR ME?
A like other career paths, the entry into this particular branch of engineering also requires you to possess certain basic traits. First and foremost, you must have a penchant for mechanical component and machinery and how these machines work. Then you must be good at physic, chemistry and mathematic. You must have also have skills such as an analytical bent of mind, logical reasoning and problem solving.
Further, you must have immense patience, physical strength, ability to work for long hours and an inventive spirit that are essential ingredients for becoming a successful mechanical engineer.
B To make Mechanical engineering your chosen career path, you must have affinity for the way different machines function. This trait can be observed from early childhood when children try to tinker around with different machinery in their immediate vicinity. Such kids often tend to take apart mechanical toys, clocks, bicycles and then try to assemble them back again.
These children are so innovative that they may even try to make things. Here, parents have a special role to play. They must understand that the child possesses an inquisitive mind that is interested in gaining knowledge about machinery and not in breaking or destroying things. Parents must encourage the child’s curiosity to know more about different gadgets and machines in and around the house.
During schooling, the quest to play around with machinery increases all the more. This curiosity often culminates with the child opting for science combination while in secondary school.
