Theory of Structures The ratio of the length and depth of a simply supported rectangular beam which experiences maximum bending stress equal to tensile stress, due to same load at its mid span, is 1/2 2/3 1/4 1/3 1/2 2/3 1/4 1/3 ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported beam carries varying load from zero at one end and w at the other end. If the length of the beam is a, the maximum bending moment will be wa²/27 wa/27 w²a wa² wa²/27 wa/27 w²a wa² 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/d (L/3d)² (L/2d)² L/2d L/d (L/3d)² (L/2d)² L/2d ANSWER DOWNLOAD EXAMIANS APP
