Theory of Structures A compound bar consists of two bars of equal length. Steel bar cross -section is 3500 mm²and that of brass bar is 3000 mm². These are subjected to a compressive load 100,000 N. If Eb = 0.2 MN/mm² and Eb = 0.1 MN/mm², the stresses developed are: b = 6 N/mm² s = 12 N/mm² b = 8 N/mm² s = 16 N/mm² b = 10 N/mm² s = 20 N/mm 2 b = 5 N/mm² s = 10 N/mm² b = 6 N/mm² s = 12 N/mm² b = 8 N/mm² s = 16 N/mm² b = 10 N/mm² s = 20 N/mm 2 b = 5 N/mm² s = 10 N/mm² ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures At any point of a beam, the section modulus may be obtained by dividing the moment of inertia of the section by Depth of the neutral axis Maximum tensile stress at the section Depth of the section Maximum compressive stress at the section Depth of the neutral axis Maximum tensile stress at the section Depth of the section Maximum compressive stress at the section ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures Pick up the correct statement from the following: In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area All of these In a loaded beam, the moment at which the first yield occurs is called yield moment In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area All of these In a loaded beam, the moment at which the first yield occurs is called yield moment In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment ANSWER DOWNLOAD EXAMIANS APP
