The following results were obtained in a tensile test on a mild steel specimen of original diameter 20 mm and gauge length 40 mm. Load at Limit of proportionality = 80 kN, Extension at 80 kN load = 0.048 mm, Load at yield point = 85 kN, Maximum Load = 150 kN. When the two parts were fitted together after being broken, the length between gauge length was found to be 55.6 mm and the diameter at the neck was 15.8 mm. The value for the estimated Young's Modulus is a. 254.65 MPa b. 212.21 kN/mm² c. 225.47 GPa d. 22.55 N/mm²
