Engineers can deal with purely theoretical problems or they can work with actual hardware.
They use scientific concepts to solve practical problems. Engineers may be required to solve complicated mathematical problems, figure out how to test a device to make sure it wont break, or write a computer program to simulate how a mechanical system will be have in the real world. Types of Engineers Mechanical - Mechanical engineers typically design machines and structures. They may design car frames and bodies or they may design the structure of a rocket or airplane. Electrical - Electrical engineers typically design electrical circuits and systems.
