Theory of Structures A steel rod 1 metre long having square cross section is pulled under a tensile load of 8 tonnes. The extension in the rod was 1 mm only. If Esteel = 2 × 106 kg/cm², the side of the rod, is 2 cm 2.5 cm 1.5 cm 1 cm 2 cm 2.5 cm 1.5 cm 1 cm 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/2d)² (L/3d)² L/2d L/d (L/2d)² (L/3d)² L/2d L/d ANSWER DOWNLOAD EXAMIANS APP
