Problem- Calculate the Knoop hardness when a 431-g load yields an indentation diagonal length of 81.0*10^-6 m.
The measured HK of some material is 187. Compute the applied load if the indentation diagonal length is 0.20 mm.
Please explain how you came up with answer I really want to understand how to calculate this
