Description 

Creation of interactive graphic displays from the numerical simulation of mechanical engineering models. Brief description of each model provided, along with varied parameters to explore models' characteristics. Conclusions drawn from use of each interactive graphic. Mathematica language introduced and interwoven with the numerical simulation of the models, which will include: robotics and mechanisms, static response of beams, control systems, measurement systems, fluid flow, vibrations, geometric modeling, finite element analysis, and nonlinear phenomena.

Goals 

To obtain a working knowledge of Mathematica to create interactive graphics that will provide an improved way to: (1) explore “what-if” scenarios; (2) examine a wide range of parameters and configuration combinations; (3) enhance one’s understanding of the model; (4) keep an audience’s attention during a presentation; and (5) exchange information within groups.
