An engineer who uses the principles of engineering, physics, and materials science to design, produce, and maintain tools, machinery, and other products. Nearly everything that has moving parts, found at home and in school, was designed by a mechanical engineer. This is one of the broadest categories of engineering, because it can include so many types of work.
The creation of objects we use every day requires attention to how it will be used and what people expect. This means people with great observation skills, attention to detail and the patients to try many things are often drawn to this problem- solving job. Computers are used extensively to design devices in engineering careers.
The manufacturing industry is the largest employer of mechanical engineers and many engineering jobs are getting very aggressive in their creativity.
