Mechanical engineers create solutions for major societal challenges including healthcare, energy, transportation, climate change, environment, world hunger, water and accommodation. They are trained to take a product from being a conceptual idea to a commercial reality. This requires skills in design and creativity to be combined with the technical ability to evaluate the stresses and strains that a product or its components will need to withstand, in addition to knowledge of the most effective manufacturing processes that will ensure the product operates safely and without failure. Mechanical engineering combines physical sciences, mathematics and materials science to design, manufacture and operate machines and devices for a diverse range of industries. Core technical areas of mechanical engineering include mechanics, dynamics, thermodynamics, materials science, fluid mechanics, structural analysis, design, and mechatronics. A mechanical engineering degree provides students with the creative skills to design a product or system, the analytical tools to ensure that designs function efficiently and economically, and the teamwork skills needed to bring a product to the marketplace.
