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 90° 60° 45° 30° 90° 60° 45° 30° ANSWER DOWNLOAD EXAMIANS APP
