The following data are obtained from a tensile test of a copper specimen. - The load at the yield point is 150 kN. - Length of the specimen is 27 mm. - The yield strength is 76 kN/mm². - The percentage of elongation is 45 %. Determine the following (i) Diameter of the specimen, ii) Final length of the specimen, iii) Stress under an elastic load of 16 kN, iv) Young's Modulus if the elongation is 2.3 mm at 16 kN and (v) Final diameter if the percentage of reduction in area is 27 %. (5 marks)
