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 + g/f)]/A [W (1 + f/ G)]/ A [W (2 + f/G)]/A (1 – g/f)/A [W (2 + g/f)]/A [W (1 + f/ G)]/ A [W (2 + f/G)]/A 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 60° 45° 30° 90° 60° 45° 30° 90° ANSWER DOWNLOAD EXAMIANS APP
