机械工程是与零件和系统的设计和制造有关的主题，这些零件和系统构成了从开罐器到喷气式飞机的各种机械设备。机械工程师设计创建所有人造产品所需的工具和过程，并且经常参与构思构想直至将其视为可用于其商业应用的成品。他们设计您认为是设备或机器的一切。发动机中使用的设备，运输中使用的组件，电力转换设备（例如现代发电厂中使用的蒸汽和风力涡轮机）以及石油和天然气钻机中使用的处理设备都属于机械工程师的职权范围。
Mechanical Engineering is a subject concerned with the design and manufacture of parts and systems that make up the range of machinery and equipment you see around you, from a can opener to a jet aircraft. Mechanical engineers design the tools and processes necessary to create all man-made products, and are often involved from conceiving of an idea right through to seeing it as a finished product ready for its commercial application. They design everything you think of as a device or machine. Devices used in engines, the components used in transportation, power conversion equipment, like the steam and wind turbines used in modern electric power plants, and processing equipment used in oil and gas rigs all come within the remit of the mechanical engineer.<br><br>Career Opportunities<br>As Mechanical Engineering is perhaps the most wide ranging of engineering disciplines, it offers diverse career opportunities. Graduates go on to work in such areas as research, industrial design, project management, environmental protection, energy production, technical sales, process control, manufacturing, aeronautics, and materials and product development. For students interested in pursuing further education, the PhD and MEngSc degrees are obtained through doing research work along with advanced study. Research students specialise in an area of research, working with a high degree of independence.
