Suppose Brinell hardness measurement is made from a nonstandard ball of diameter 5 mm. If the load applied in 10 mm standard ball is 3000 kg, then what load should be applied on the 5 mm ball to get the consistent reading in hardness measurement?

Suppose Brinell hardness measurement is made from a nonstandard ball of diameter 5 mm. If the load applied in 10 mm standard ball is 3000 kg, then what load should be applied on the 5 mm ball to get the consistent reading in hardness measurement? Correct Answer 750 kg

For the consistency in the result the; P1/D12=P2/D22 To compare the values 3000/100=P2/25 P2=750 So the applied load should be 750 kg.
