Mechanical engineers use computer systems to test designs and execute virtual simulations to determine how a machine will work or interact with connected systems, as well as computer-aided design (CAD) and computer-aided manufacturing (CAM) programs, as modern professional engineers. Dynamics, mechanics, thermodynamics, structural analysis, and electricity are all skills that mechanical engineers must possess.

Mechanical engineering sometimes overlaps with other engineering fields such as civil, chemical, industrial, and electrical.

While the specifics of the job will vary based on where you work, a mechanical engineer will often do the following:

• Analyzing issues and mechanical device failures to determine the reason and solution
• Mechanical device design, redesign, or adaptation
• Create and test mechanical prototypes, modifying designs in response to test results.
• Control manufacturing processes.
• Mechanical physics, forces, rotation, vibrations, and velocity are often required for this work.

Where do Mechanical Engineers Work?

Mechanical engineers work in a variety of settings depending on the business they work in. Employment prospects can be found practically anywhere there is innovation, such as in the aerospace, automotive, chemical, construction, consumer goods, defense, electronics, marine, metals and minerals, pharmaceutical, rail, and utilities industries.

Mechanical engineers are also engaged in non-engineering roles, both within and outside of engineering. Teaching, administration, technical consultancy and sales, publishing/science journalism, government, military, medicine, research, and other fields may be included.

Most mechanical engineers work in an office setting, though they may travel to sites to investigate problems or service equipment.
