Question for engineers with a degree in mechanical engineering: I have a degree in mechanical engineering and work as a design engineer with mostly mechanical systems. I passed my FE/EI exam. My question is does having your PE certification open a lot of doors for mechanical engineers? I know having your PE is critical for civil/structural engineers. I'm trying to decide if I want to pursue my PE certification. What could I really do with it? I would love some input from engineers with his or her PE. Thanks!
