What is the difference between the "Open End" and "Closed End" conditions? Which case

experiences "uniaxial state of stress" and which case experiences "biaxial state of stress"? Explain

each case in detail including equations if necessary.

With the data obtained, plot on ONE GRAPH the hoop stress $($in MPa$)$ versus hoop strain $($in $)$

for gauges $1$ and $6.$ Determine Young's Modulus $E$ for both gauges. Use these $E$ values to determine

an average $E.$

With the data obtained, plot the longitudinal strain $($in $)$ versus hoop strain $($in $).$ With the best

straight line fit, find Poisson's Ratio $(v).$

Based on the experimental results of $E$ and $v,$ what is the material of the thin cylinder?

Compare the experimental results of $E$ and $v$ with the published value of the material? Comment.
