///Find Stress in square metal bar
//Input data
clc;
clear;
A1=50*50*10^-6; //Area ofsquare metal bar in mm**2
Pc=600*10^3; //Axial compress laod in KN
L1=200*10^-3; //Gauge length of metal bar in mm
deltaLc=0.4*10^-3; //Contraction length of metal bar in mm
deltaLlateral=0.05*10^-3; //Lateral length of metal bar in mm
//Calculation
sigmac=Pc/A1; //Stress in square metal bar
ec=deltaLc/L1; //Longitudinal or linear strain in square metal bar
E1 =sigmac/ec; //Smodule of elasticity
elateral=deltaLlateral/L1; //Lateral strain in square metal bar
poissonsratio=elateral/ec;
//Output
printf('stress in bar=%f N/m^2 \n',sigmac);
printf('longitudinal or linear strain in square metal bar= %f \n',ec);
printf('module of elasticity= %f N/m^2 \n',E1);
printf('lateral strain in square metal bar=%f \n',elateral);
printf('poissons ratio=%f \n',poissonsratio);
