Unformatted text preview: where L = load, kg D = diameter of indentor, mm d = diameter of indentation, mm SPECIFICATIONS Specifications: Write a Matlab Worksheet where the values of L, D, and d, are written in the beginning of the matlab worksheet and then computes and displays the Brinell Hardness. INPUTS and DISPLAYING INPUTS clc L = 3000; D = 10; d = 7.2; fprintf( '\nThe Load Applied in kgf is L=%d' ,L) fprintf( '\nThe Diameter of the Indented Load in mm is D=%d' ,D) fprintf( '\nThe Diameter of the Indent in mm is L=%d' ,d) The Load Applied in kgf is L=3000 The Diameter of the Indented Load in mm is D=10 The Diameter of the Indent in mm is L=7.200000e+000 CODE %Calculating the hardness using the formula HB=L/((pi*D/2)*(D-sqrt(D^2-d^2))); DISPLAYING OUPUTS fprintf( '\nThe Hardness of the Material is HB=%d' ,HB) The Hardness of the Material is HB=6.240841e+001 Published with MATLAB® 7.10...
