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 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
Your calculations seem fine, what is the unit of the area? You can also make sure that the force is in N, not in kN or something.
The unit of area is m^2, and the force was 6.009 KN so 6009 N. Its way off the typical value though, it doesnt make sense?
