Mechanical engineers design, develop, build, test, and inspect mechanical devices and systems, such as machines, tools, engines, heating and cooling systems, transportation systems, and robotics. These individuals are creative thinkers who are responsible for several things such as producing outline designs, testing, and evaluating theoretical designs, and they produce effective solutions to emerging problems. 

To be a successful mechanical engineer, you must be a highly creative individual who can come up with innovative solutions to problems. 

Mechanical engineers usually work in offices where the computer plays a major role. People that choose this career have options to specialize in areas such as transportation equipment, fluid mechanics, or even construction.
