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/d (L/3d)² (L/2d)² L/2d L/d (L/3d)² (L/2d)² L/2d ANSWER DOWNLOAD EXAMIANS APP
