Theory of Structures A steel bar 5 m × 50 mm is loaded with 250,000 N. If the modulus of elasticity of the material is 0.2 MN/mm² and Poisson’s ratio is 0.25, the change in the volume of the bar is: 3.125 cm³ 4.125 cm² 2.125 cm³ 1.125 cm³ 3.125 cm³ 4.125 cm² 2.125 cm³ 1.125 cm³ ANSWER DOWNLOAD EXAMIANS APP
