MEAM.Design - MEAM 247 - P3: Concentrate - Strain Data

This data was taken as we slowly loaded the plate to 2000 lb, held the load for a while, then slowly unloaded. The strain gauge data was taken at approximate 10-second intervals, and the values reported are "microstrain", which is one-millionth of regular strain. The gauges were located in the following positions along the H-H line, with distances measured in inches away from the center of the hole, and orientation indicating whether the gauge was aligned vertically (V) or horizontally (H):

Gauge # Distance (inches) Orientation
1 3.39 H
2 3.25 H
3 1.50 H
4 0.75 H
5 3.39 V
6 2.01 V
7 1.20 V
8 0.67 V
9 4.79 H
10 4.79 V

Having looked at the data, I encourage you to approach this with a good dose of scientific skepticism! (if time permits, I will gather better data.)
