Theory of Structures A lift of weight W is lifted by a rope with an acceleration f. If the area of cross-section of the rope is A, the stress in the rope is (1 – g/f)/A [W (2 + f/G)]/A [W (1 + f/ G)]/ A [W (2 + g/f)]/A (1 – g/f)/A [W (2 + f/G)]/A [W (1 + f/ G)]/ A [W (2 + g/f)]/A ANSWER DOWNLOAD EXAMIANS APP

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 = 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 b = 6 N/mm² s = 12 N/mm² ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures Pick up the correct statement from the following: In a loaded beam, the moment at which the first yield occurs is called yield moment 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 All of these In a loaded beam, the moment at which the first yield occurs is called yield moment 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 All of these ANSWER DOWNLOAD EXAMIANS APP
