A steel bar of 2 cm diameter & 1 m initial length is used as a structural member in an engineering design. The applied structural tensile load on the bar is 90,000 N. The yield strength and tensile strength of the steel bar are 600 MPa & 750 MPa, respectively. Under the applied tensile load of 204 kN, the bar generates a deformation of 3.25 mm. Calculate the modulus of elasticity.
