Mechanical engineering is the discipline that applies engineering physics, engineering mathematics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.

Mechanical engineers typically do the following:

  • Analyze problems to see how mechanical and thermal devices might help solve a particular problem.
  • Design or redesign mechanical and thermal devices or subsystems, using analysis and computer-aided design.
  • Investigate equipment failures or difficulties to diagnose faulty operation and to recommend remedies.
  • Develop and test prototypes of devices they design.
  • Analyze the test results and change the design or system as needed.
  • Oversee the manufacturing process for the device.
