Stress=force per unit CSA
=1000000000/3•14
=3.33×1000000
elongation=stress×original lenght/Young's mod
=3.33×1000000×1/2×10(power)11
=3.33×10(power)-5
percentage=elongation/total length×100
=3.33×10(power)-3/1%
=1000000000/3•14
=3.33×1000000
elongation=stress×original lenght/Young's mod
=3.33×1000000×1/2×10(power)11
=3.33×10(power)-5
percentage=elongation/total length×100
=3.33×10(power)-3/1%
