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/2d)² L/2d L/d (L/3d)² (L/2d)² L/2d L/d (L/3d)² ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures Pick up the correct statement from the following: The moment of inertia is calculated about the axis about which bending takes place If tensile stress is less than axial stress, the section experiences compressive stress If tensile stress is equal to axial stress, the section experiences compressive stress All of these The moment of inertia is calculated about the axis about which bending takes place If tensile stress is less than axial stress, the section experiences compressive stress If tensile stress is equal to axial stress, the section experiences compressive stress All of these ANSWER DOWNLOAD EXAMIANS APP
