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: 4.125 cm² 3.125 cm³ 1.125 cm³ 2.125 cm³ 4.125 cm² 3.125 cm³ 1.125 cm³ 2.125 cm³ ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported uniform rectangular bar breadth b, depth d and length L carries an isolated load W at its mid-span. The same bar experiences an extension e under same tensile load. The ratio of the maximum deflection to the elongation, is (L/3d)² L/2d L/d (L/2d)² (L/3d)² L/2d L/d (L/2d)² ANSWER DOWNLOAD EXAMIANS APP
