1) Deviations To find the maximum load to avoid failure, we took the average dimensions of the beams to calculate it. 4) POISSONS The aluminum bar had two strain gauges located at the same distance away from the base. One is placed laterally and the other longitudinally. To calculate poisson’s ratio we use the following equation: Distanc e Weight(g) Lat.Strai n Long. Strain Poisons Ratio 30.2cm 1672.91 - 0.000090 0.000268 0.336 3472.62 - 0.000187 0.000583 0.321 4486.63 - 0.000237 0.000757
