Mechanical engineers are problem-solvers, designers, and creators. They understand materials, solid and fluid mechanics, thermodynamics, design, control, instrumentation, and production. Engineers in this area can recognize emerging issues, come up with novel solutions, and create and test prototypes of their designs.<br><br>As a mechanical engineer, you’ll create products and technologies that meet human needs. These can span a range from large to small: enormous power turbines and manufacturing robots on one end, nanoscale devices and systems on the other. No matter what their size, the devices you create and refine could have an impact on energy, transportation, space exploration, the environment, health care, aerospace, and more.
