It is also one of the most well-known fields. There are many different things a mechanical engineer does for their work and job. One of these things has to do with where a mechanical engineer would work. A mechanical engineer usually works in an office. Some of them do go outside for their jobs. Mechanical engineers that work outside usually do work such as visiting job sites to observe problems or conditions of things. Also, they might have to meet with customers or attend to meetings for a project, or in the development of construction. Another thing that has to do with a mechanical engineer is what tools they use for their work. Mechanical engineers use computers (Word), CAD, email, software to calculate heating, cooling, and ventilation. A mechanical engineer must have certain degrees. A mechanical engineer needs a bachelor of science in mechanical engineering. A mechanical engineer makes roughly about 53,000 to 86,000 dollars a year. This all depends on how long and what degree the engineer has or is. The areas of specialization include biomedical, combustion, ground vehicle systems, Mechanical design, and much more. Mechanical engineers require certain high school classes. This includes Algebra, Geometry, Trig, Chemistry, Biology, Physics, Pre- Calc or Calc. Mechanical Engineering is very important to our everyday life. If we did not have it then we wouldn’t have a lot of things. Mechanical Engineers are the ones who build cars, planes, rockets, and many more things that move. Imagine what life would be without these. Interview Charles Depase 1.

I think it is the most interesting type of engineering there is and if I were to be an engineer, I would choose mechanical. This project was difficult, but I learned a lot from it. I learned that it takes a lot to become an engineer but that it’s totally worth it. I also learned what I would need to take in order to become an engineer. I found this project very useful.
