Mechanical engineers provide efficient solutions to the development of processes and products, ranging from small component designs to extremely large plant, machinery or vehicles. They can work on all stages of a product, from research and development to design and manufacture, through to installation and final commissioning. Most industries rely on a form of mechanical systems and mechanical engineering is thought to be one of the most diverse of all engineering disciplines. Due to this, there are employment opportunities in a wide range of sectors, including: manufacturing; power; construction; medical. Mechanical engineers can be involved in the management of people and resources, as well as the development and use of new materials and technologies
