I am trying to calculate youngs modulus of elasticity for results from a tensile test but cant seem to get a figure close to that of the common figure for the material(adsbygoogle = window.adsbygoogle || []).push({});

Material 0.1% carbon steel

Area = 20 x 10^{-6}

Yield force = 6009N

Length increase at yield force = 0.537mm = 0.000537m

Original length = 25.6mm = 0.0256m

E = σ/ε

E = (6006/20x10^{-6}) / (0.000537/0.0256)

E = 14.32 x 10^{9}

Typical value = 207 x 10^{9}

Iv obviously went very wrong somewhere but i dont know where

Thanks
