Question

Problem 2: Vickers hardness test was conducted on a material with an applied laod of 5kg. If the measured diagonal distances of the indentation made by the diamond indenter, dl and d2 were 190.9 um and 192.6 um respectivelyte Windows calculate: Go to Settings to activate Windo 1. The Vickers hardness of the material (HV)
