//Given
//Variable declaration
A=8*8 //Area of section in sq.mm
P=7000 //Axial pull in N
Ldo=8 //Original Lateral dimension in mm
Ldc=7.9985 //Changed Lateral dimension in mm
C=0.8e5 //modulus of rigidity in N/sq.mm
//Calculation
lat_strain=(Ldo-Ldc)/Ldo //Lateral strain
sigma=P/A //Axial stress in N/sq.mm
mu=(1/((sigma/lat_strain)/(2*C)-1)) //Poisson's ratio
E=((sigma/lat_strain)/((sigma/lat_strain)/(2*C)-1)) //Modulus of elasticity in N/sq.mm
//Result
printf("\n Modulus of elasticity = %.4e N/mm^2",E)
