An axial load of 430 kN is slowly applied to length direction of a 25 mm (height) ×100 mm (width) ×2500 mm (length) rectangular bar. When loaded (the action is elastic), the 100 mm side measures 99.965 mm, and the length has increased 2.5 mm. Determine Poisson's ratio and Young's modulus for the material. Show work for full credit.
