As shown in Figure Q2(a), a 700 mm long, 18 mm diameter rod made of a homogeneous, isotropic material is observed to increase in length by 500 um, and to decrease in diameter by 3.2 um when subjected to an axial 18 kN load. Determine the modulus of elasticity and Poisson's ratio of the material. (5 marks)
