Theory of Structures A square column carries a load P at the centroid of one of the quarters of the square. If a is the side of the main square, the combined bending stress will be 4p/a² p/a² 2p/a² 3p/a² 4p/a² p/a² 2p/a² 3p/a² ANSWER DOWNLOAD EXAMIANS APP
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 45° 30° 60° 90° 45° 30° 60° 90° ANSWER DOWNLOAD EXAMIANS APP
