Theory of Structures For determining the support reactions at A and B of a three hinged arch, points B and Care joined and produced to intersect the load line at D and a line parallel to the load line through A at D’. Distances AD, DD’ and AD’ when measured were 4 cm, 3 cm and 5 cm respectively. The angle between the reactions at A and B is 60° 30° 45° 90° 60° 30° 45° 90° 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 w²a wa²/27 wa/27 wa² w²a wa²/27 wa/27 ANSWER DOWNLOAD EXAMIANS APP

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 2/3 1/4 1/2 1/3 2/3 1/4 1/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A short column (30 cm × 20 cm) carries a load P 1 at 4 cm on one side and another load P2at 8 cm on the other side along a principal section parallel to longer dimension. If the extreme intensity on either side is same, the ratio of P1 to P2 will be 8/5 2/3 5/8 3/2 8/5 2/3 5/8 3/2 ANSWER DOWNLOAD EXAMIANS APP
