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 1/3 1/4 2/3 1/2 1/3 1/4 2/3 1/2 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 w²a wa/27 wa² wa²/27 w²a wa/27 wa² wa²/27 ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A cantilever of length ‘L’ is subjected to a bending moment ‘M’ at its free end. If EI is the flexural rigidity of the section, the deflection of the free end, is ML²/3EI ML²/2EI ML/EI ML/2EI ML²/3EI ML²/2EI ML/EI ML/2EI ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures Pick up the correct statement from the following: In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment In a loaded beam, the moment at which the first yield occurs is called yield moment All of these In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment In a loaded beam, the moment at which the first yield occurs is called yield moment All of these In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area ANSWER DOWNLOAD EXAMIANS APP
