//Given
//Variable declaration
D=25 //Diameter of brass rod in mm
P=50*10**3 //Tensile load in N
L=250 //Length of rod in mm
dL=0.3 //Extension of rod in mm
//Calculation
A=(%pi/4)*(D**2) //Area of rod in sq.mm
sigma=(P/A) //Stress in N/sq.mm
e=dL/L //Strain
E=(sigma/e) //Youngs Modulus in N/sq.m
//Result
printf("\n Youngs Modulus of a rod,E = %0.3f GN/m^2",E*(10**-3))
