During their mechanical engineering bachelor's programs, future practitioners study how to design, test, and build complex machinery to automate processes. Other types of engineers use these applications in their own work, including industrial, chemical, civil, and aerospace professionals. As such, you'll be exposed to the principles of other disciplines during a mechanical engineering program, such as materials science, nanotechnology, electronics, and manufacturing processes.
Almost all master's degrees require you to select a concentration, which might include thermofluids, design, or controls and manufacturing. This allows you to focus your education on courses that may help you seek the type of job you prefer.
