Electrical engineers also work for engineering and architectural services companies and the government. Mechanical Engineering Mechanical engineering is the second oldest and second largest engineering profession. It is also one of the broadest. There are over 30 subdivisions of mechanical engineering that are recognized by the American Society of Mechanical Engineers. Advanced Energy Systems, Heat Transfer, Nuclear Engineering, and Safety Engineering and Risk Analysis are just a few of the many subdivisions.
Mechanical engineers do many different things.
Many mechanical engineers are concerned with the use of energy from natural sources and its economical conversion into other useful energy. While some design machines and process materials into products ranging from air conditioners to cars, others educate and train technicians to deal with mechanical systems. Since mechanical engineering is such a broad field, these engineers work in many places. Such places include manufacturing, engineering and architectural services, and the federal government. There are many resources a person studying engineering can go to for help in finding career direction.
