Frequently asked questions about the role and responsibilities of mechanical engineers

Mechanical engineersspend most of their day working on a computer, and solve problems by using math — lots of math. Mechanical engineers design, develop, and test mechanical devices such as engines, machines, or robots. They may specialize in particular fields including thermal engineering, manufacturing engineering, aerospace engineering, and biomedical engineering.

A career as a mechanical engineer can be very rewarding because you will be able to help people by designing machines that improve their quality of life. Mechanical engineering is also an excellent choice because it can lead to a career in other fields like business, manufacturing, and accounting if one chooses not to work as a mechanical engineer.

Working as a mechanical engineer can be hard, and you may have to work long hours to meet deadlines or solve problems. You also have to be willing to do some physical work and spend a lot of time doing paperwork. Mechanical engineers are often required by law to pursue professional development by completing continuing education courses, even after obtaining their degree.
