Mechanical engineering is a diverse subject that derives its breadth from the need to design and manufacture everything from small individual parts and devices (e.g., microscale sensors and inkjet printer nozzles) to large systems (e.g., spacecraft and machine tools). The role of a mechanical engineer is to take a product from an idea to the marketplace. Mechanical engineering deals with anything that moves, including the human body, a very complex machine. Mechanical engineers learn about materials, solid and fluid mechanics, thermodynamics, heat transfer, control, instrumentation, design, and manufacturing to understand mechanical systems. Specialized mechanical engineering subjects include biomechanics, cartilage-tissue engineering, energy conversion, laser-assisted materials processing, combustion, MEMS, microfluidic devices, fracture mechanics, nanomechanics, mechanisms, micropower generation, tribology (friction and wear), and vibrations.
A process engineer changes materials from one form to another so that they can be used in new and interesting ways. A mechanical engineer will design and build the machines that heat, cool, liquefy, harden or soften substances.
Dynamic systems need to be controlled. Typical applications of DSC include novel transducer designs, biomechanics at the cellular and human scale, dynamics and control of power and vehicle systems, and innovations in signal and information theory. These engineers are needed in a vast number of areas aerospace and transportation, biomedical equipment, production machinery, energy and fluid power systems, expert systems and environmental systems.
