Mechanical engineer?

            Mechanical engineers create and build mechanical devices. They apply the fundamentals of science and math to create practical, useful solutions that the rest of us can use.The diverse mechanical engineering field can be divided in a variety of ways in terms of job functions. Some of the most common functions relate to these areas of technology, but not all do. Among these fields are:

• Product Design
• Research and Development
• Manufacturing
• Systems management
• Energy

        In most of these fields, the mechanical engineer is concerned with heat utilization or machine design in other words, harnessing or creating energy. Heat utilization techniques are applied in boilers, air conditioners, and refrigeration. Machine design is more focused on hardware, automobile engines, and computers.
