DEFINE OPERATIONALLY OF HARDNESS OF ALLOY
                                   Hardness of alloy is the diameter of
                                   dent on alloy measured when 1 kg
                                   of weight is dropped onto it. The
                                   smaller the diameter of dent
                                   formed on the alloy, the harder the
                                   alloy.
