Mechanical engineering covers the most fundamental basis of the areas with the most extensive range of subjects of the engineering branches.Mechanical Engineers master the development, design, production planning and control application of all kinds of mechanical systems, machines and machine components. Thus, mechanical engineers play major role in of large projects, such as the construction of bridges, dams, factories, as well as in the production apparatus, such as small car, etc, ranging from a wide area of manufacturing, where technology is required. Today, the working areas of mechanical engineers are continuously expanding with the appearance of new industries and with new developments in old industries and new developments in energy resources.
