c) You have been given a sample of a malfunctioned airplane wing, which is made of aluminium. The company offered you an access to a tensile testing equipment and magnetic particles inspection equipment to investigate the malfunctioning behaviour. The results of your experiment were as follows: Load (KN) Extension (mm) 13 0.2 29 0.4 56 0.7 0.9 1.5 2.5 70 95 110 132 147 8.5 145 10 130 Table 1: Tensile Testing Results (Load Extension) 12 1. Given that the length of the sample is 90 mm and the diameter of it is 7 mm. i Draw the stress stain diagram. Find the yield stress (in KN/mm²). Find the ultimate tensile stress (in KN/mm²). iv. ii. iii. At a point on the proportional section, calculate the modulus of Elasticity (Young's modulus). Hint: when calculating the Elasticity, use the stress strain numbers, not the force numbers
