A solid circular rod is subjected to an axial load of P = 285kN. The diameter of the rodis d = 30 mm, and its length is L = 900 mm. After load P isapplied, the elongation ofthe rod is  = 3.20 mm, and its diameter becomes d’ = 29.967 mm.Determinea. the modulus of elasticity for the material.b. Poisson’s ratio for the material.
