                                                                                                                     2
              A steel tensile specimen has a cross section area of 100mm and a
              gauge length of 50mm,the gradient of the elastic section
              410x10 N/mm. determine the modulus of elasticity
                          3





              Solution:


                                σ                                    50
                            E= =    = 410    103                          = 205 000N/mm               2
