A piece of material 15 cm long by 2.5 cm square is in compression under a load 100kN. If the modulus of elasticity of the material is 105 GPa and Possion's ratio is 0.25, find the alternation in length if all lateral strain is prevented by the application of uniform lateral external pressure of suitable intensity

A Piece of material 15 cm long by 2.5 cm square is in compression under a load 100 KN. If the modulus of elasticity of the material s 105 GPa and Poisson’s ratio is 0.25, find the alteration in length if all lateral strain is prevented by the application of uniform lateral external pressure of suitable intensity.
