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) 13 29 Extension (mm) 0.2 0.4 56 70 95 0.7 0.9 1.5 110 2.5 132 8.5 10 12 147 145 130 Table 1: Tensile Testing Results (Load Extension) 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. ii. Find the yield stress (in KN/mm2). Find the ultimate tensile stress (in KN/mm²). iii. iv. 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
