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° 90° 30° 45° 60° 90° 30° 45° ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A cantilever of length ‘L’ is subjected to a bending moment ‘M’ at its free end. If EI is the flexural rigidity of the section, the deflection of the free end, is ML/2EI ML/EI ML²/2EI ML²/3EI ML/2EI ML/EI ML²/2EI ML²/3EI ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures If Q is load factor, S is shape factor and F is factor of safety in elastic design, the following: Q = S – F Q = F – S Q = S + F Q = S × F Q = S – F Q = F – S Q = S + F Q = S × F ANSWER DOWNLOAD EXAMIANS APP
