Theory of Structures A simply supported beam A carries a point load at its mid span. Another identical beam B carries the same load but uniformly distributed over the entire span. The ratio of the maximum deflections of the beams A and B, will be 5/8 2/3 8/5 3/2 5/8 2/3 8/5 3/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures If E, N, K and 1/m are modulus of elasticity, modulus of rigidity. Bulk modulus and Poisson ratio of the material, the following relationship holds good All of these E = 2N (1 + 1/m) E = 3K (1 – 2/m) (3/2)K (1 – 2/m) = N (1 + 1/m) All of these E = 2N (1 + 1/m) E = 3K (1 – 2/m) (3/2)K (1 – 2/m) = N (1 + 1/m) 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 411 N mm 711 N mm 511 N mm 611 N mm 411 N mm 711 N mm 511 N mm 611 N mm ANSWER DOWNLOAD EXAMIANS APP
