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/d (L/2d)² (L/3d)² L/2d L/d (L/2d)² (L/3d)² ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A truss containing j joints and m members, will be a simple truss if m = 2j – 3 m = 3j – 2 j = 2m – 3 j = 3m – 2 m = 2j – 3 m = 3j – 2 j = 2m – 3 j = 3m – 2 ANSWER DOWNLOAD EXAMIANS APP
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 511 N mm 411 N mm 711 N mm 611 N mm 511 N mm 411 N mm 711 N mm 611 N mm ANSWER DOWNLOAD EXAMIANS APP
