# Experimental Data

The experimental data provided in this document was gathered by summer students in the Geometry Center's Summer Institute for undergraduates.

The "beams" used were meter sticks:

• Aluminum beam
• height = 0.002 m
• width = 0.029 m
• Pine beam
• height = 0.008 m
• width = 0.026 m
Data for a total of 17 experiments are presented here. The error in measurement of the deflection is approximately +/-0.001 m (=1 mm).

Please contact the Calculus Development Team if you have experimental data that you would like to share.
