  2. About Eng. Design Teams • Consist of Members with a Mix of Backgrounds and Training: • Scientists: Have strong training in math and science which emphasizes the theoretical. Scientists ask "Why?" questions.

  3. About Eng. Design Teams • Engineers: Attempt to do something useful with scientific theories and principles, called design, i.e., a creative process that produces in a new device, system, structure, or process that satisfies a specific need. • Technologists: Do much of the actual implementation of the engineering designs, like CAD drawings, testing, data taking and reduction, and directing craftspeople during fabrication. • Craftspeople: Are the practical or implementation end of the spectrum. They primarily manufacture or assemble the products designed by the rest of the team, e.g., welders, machinists, etc.

  19. Developing Models and Prototypes • All modeling can be broken down into one of two categories: • Descriptive Models: Depict ideas, products, and processes in a way that is recognizable. The goal is to show what a design would look like if it were created. • Examples: Engineering drawings, 3D computer models, or scale models • Predictive Models: Used to test and understand how designs ideas, products, and processes will perform. May bear little or no resemblance to the overall design. • Examples: Mathematical equations or graphs showing a relationship between design requirements

  20. Developing Models and Prototypes • Scale models are one of the most basic and generally useful because they are very much hands-on and provide a good feel for a design and its features • Computer simulation and animation are two other common model types
