//Variable declaration
ml=57800 //load(N)
d=10*10**-3 //diameter(m)
D=5 //diameter after fracture(mm)
l=50 //guage length(mm)
L=55 //length after fracture(mm)
//Calculation
ts=ml/(%pi*(d/2)**2) //ultimate tensile strength(MPa)
de=(L-l)*100/l //ductility % of elongation(%)
dr=((2*D)**2-D**2)*100/(2*D)**2 //ductility % of reduction(%)
t=(2/3)*ts*de/100 //modulus of toughness(Pa)
//Result
printf("\n ultimate tensile strength is %0.0f MPa",ts/10**6)
printf("\n modulus of toughness is %0.0f *10**6 Pa",t/10**6)
