A mechanical engineer deals with the physical reality of things such as engines, vehicle bodies, electric generators, cranes, air conditioners, airplane wings, pumps, and robots. He or she is?faced with the challenges and uncertainties that come with complex products and systems, which often transcend multiple disciplines. In addition to using the classical and modern principles of engineering science, the mechanical engineer must be able to devise economically viable, environmentally friendly, and socially acceptable solutions to problems. The analytical problem solving skills combined with sound technical fundamentals of the mechanical engineering degree can also form the basis for successful careers in fields such as business, law and medicine.
