Theory of Structures A material is said to be perfectly elastic if It does not regain its original shape at all It regains its original shape on removal of the load None of these It regains its original shape partially on removal of the load It does not regain its original shape at all It regains its original shape on removal of the load None of these It regains its original shape partially on removal of the load 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
