Theory of Structures A steel bar 5 m × 50 mm is loaded with 250,000 N. If the modulus of elasticity of the material is 0.2 MN/mm² and Poisson’s ratio is 0.25, the change in the volume of the bar is: 4.125 cm² 3.125 cm³ 2.125 cm³ 1.125 cm³ 4.125 cm² 3.125 cm³ 2.125 cm³ 1.125 cm³ 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° 90° 60° 30° 45° 90° 60° 30° ANSWER DOWNLOAD EXAMIANS APP
