Plot a load - displacement curve for the slender rod from the Euler buckling experiment.
From the length of the rod and the measured value of the buckling load compute the product (EI) for the material. Using the cross sectional area of the rod, compute the second moment of area, I, and determine E from the previous data. How does this value of Young's modulus compare to the published values?

Obtain a load - displacement curve for the plastic buckling of the tubular sample. Plot this data and compute the work done during the collapse of the tube. Estimate (or measure) the temperature rise of the tube during deformation. Compare your estimate to the temperature rise you compute assuming that the work is adiabatic. Evaluate this material as a potential crash energy absorber in a vehicle that weighs 1000 kg.
