(a) What is the indentation diagonal length when a load of 0.60 kg produces a Vickers hardness (HV) of 400? (b) Calculate the Vickers hardness when a 700 g load yields an indentation diagonal length of 0.050 mm. (c) An annealed AISI 4340 steel was determine to have a Brinell hardness of HB = 216. Estimate the tensile strength of this steel in MPa.
