Mechanical engineering is about turning energy into motion and power. It covers the generation, conversion, transmission and use of mechanical and thermal energy, and includes the design, construction and operation of devices and systems. It also involves the behaviours of solids, liquids and gases when forces are applied and when they are heated and cooled.

As a mechanical engineer you could work in research and development, product and process design, technical sales and support, manufacturing, field and test engineering, project management, systems design and power plant operations and quality control. You could work in the petrochemical, automotive, transportation, aerospace, electronic, mining and robotic industries.
