Problem 1: A round bar with a diameter of 29 mm, and 4880 mm in length was under tensile test to determine the mechanical properties of the material. The following table shows the load versus strain data collected from the testing machine and a strain gauge applied on the bar in the loading direction. The measured percentage elongations were 19.4 % and 14.2 % on gauge lengths of 100 mm and 200 mm respectively. Assume: the elongations include the necking:...

You have a material of a length of 10mm and a diameter of 0.2 mm. When you apply a tensile force of 1.1*104N, this material elongates to the length of 15mm. You measure a diameter of the elongated sample and you find that it is now 0.16 mm. Assuming the deformation remains elastic, calculate Poisson ratio and Young’s modulus of this material (in GPa)
