FEA Demo: Tuning Fork (with voice over)

Classroom demonstration of FEA Modal Analysis in Autodesk Inventor Pro, for Intro Engineering students at UVa. A real tuning fork, made of aluminum, is scanned with a regular desktop copier, and used to template a CAD model. Modal analysis is applied, and the frequency predicted for the lowest frequency mode is remarkably close to the correct value (128 Hz).
