Mechanical engineers serve humanity by solving problems and making life better, contributing to overall economic development and protecting the environment. Broadly speaking, mechanical engineers study, design and fabricate devices and components that move and use energy (i.e., almost everything). Some examples include automobiles, aircraft, power plants, robots, pollution control systems, environmental remediation systems, children’s toys, motors, engines, and air conditioning and refrigeration systems. Mechanical engineers play a role in shaping our everyday experience, from using ballpoint pens to riding in airplanes. If you have a sense of curiosity about the world and a desire to help improve society, a mechanical engineering major might be for you.
