For determine the Hardness of the mild steel, Vickers test is used. The indenter used in Vickers Hardness test is square based diamond pyramid indenter with an apex angle of 136°. The length of each diagonal of projected indentation area is 0.4 mm. The indentations for applied on the diamond indenter is 1000 N. What will be the calculated Vickers hardness number? (g = 10 m/s2)
