The following data are obtained from a tensile test of a copper specimen. - The load at the yield point is 142kN. - Length of the specimen is 25 mm. - The yield strength is 87kN/mm^2
The percentage of elongation is 47%. Determine the following (i) Diameter of the specimen, ii) Final length of the specimen, iii) Stress under an elastic load of 17kN, iv) Young's Modulus if the elongation is 1.1 mm at 17kN and (v) Final diameter if the percentage of reduction in area is 20%.
