MECHANICAL ENGINEERING

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

Mechanical engineering is one of the broadest engineering fields. Mechanical engineers design and oversee the manufacture of many products ranging from medical devices to new batteries. Mechanical engineers design power-producing machines, such as electric generators, internal combustion engines, and steam and gas turbines, as well as power-using machines, such as refrigeration and air-conditioning systems. Mechanical engineers design other machines inside buildings, such as elevators and escalators. They also design material-handling systems, such as conveyor systems and automated transfer stations. Like other engineers, mechanical engineers use computers extensively. Mechanical engineers are routinely responsible for the integration of sensors, controllers, and machinery. Computer technology helps mechanical engineers create and analyze designs, run simulations and test how a machine is likely to work, interact with connected systems, and generate specifications for parts.
