Theory of Structures A steel bar 20 mm in diameter simply-supported at its ends over a total span of 40 cm carries a load at its centre. If the maximum stress induced in the bar is limited to N/mm², the bending strain energy stored in the bar, is 611 N mm 511 N mm 411 N mm 711 N mm 611 N mm 511 N mm 411 N mm 711 N mm 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° 30° 60° 45° 90° 30° 60° ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported uniform rectangular bar breadth b, depth d and length L carries an isolated load W at its mid-span. The same bar experiences an extension e under same tensile load. The ratio of the maximum deflection to the elongation, is L/2d (L/3d)² L/d (L/2d)² L/2d (L/3d)² L/d (L/2d)² ANSWER DOWNLOAD EXAMIANS APP
