You generally need at least a bachelor's degree in mechanical engineering to enter this field. It takes four or five years to earn a bachelor's degree in engineering. Some programs include periods of work experience along with formal classes. Many engineers go on to obtain advanced degrees in a specialized field of engineering or business administration. Engineers often continue their education throughout their careers to remain aware of new developments in their field. Most employers encourage engineers to take formal courses that help engineers to improve their job performance. Some even pay the cost of tuition for these courses. In addition, mechanical engineers read and study professional and trade journals.
Engineers whose work affects life, health, or property or who offer their services to the public must be licensed by the state in which they work. They generally need a degree from an approved engineering college, about four years of work experience as an engineer, and a passing grade on a state examination before being licensed as a professional engineer.
Other Qualifications
Engineers should be creative, inquisitive, analytical, and detail oriented. They should be able to work as part of a team and to communicate well, both orally and in writing. Communication abilities are becoming increasingly important as engineers frequently interact with specialists in a wide range of fields outside engineering.
Nature of the Work

Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between scientific discoveries and the commercial applications that meet societal and consumer needs.
Mechanical engineers research, design, develop, manufacture, and test tools, engines, machines, and other mechanical devices. Mechanical engineering is one of the broadest engineering disciplines. Engineers in this discipline work on power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines. They also work on power-using machines, such as refrigeration and air-conditioning equipment, machine tools, material handling systems, elevators and escalators, industrial production equipment, and robots used in manufacturing. Mechanical engineers also design tools that other engineers need for their work. In addition, mechanical engineers work in manufacturing or agriculture production, maintenance, or technical sales, and many become administrators or managers.
Work Environment
Mechanical engineers spend part of their time in clean, well-lighted office buildings. At other times they work at construction sites or in noisy factories. Working conditions vary widely since mechanical engineers are employed in so many different kinds of jobs. Their basic workweek is usually forty hours. Overtime is necessary in some jobs, especially when project deadlines must be met.
