Theory of Structures The ratio of the length and depth of a simply supported rectangular beam which experiences maximum bending stress equal to tensile stress, due to same load at its mid span, is 2/3 1/3 1/4 1/2 2/3 1/3 1/4 1/2 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 711 N mm 411 N mm 611 N mm 511 N mm 711 N mm 411 N mm 611 N mm ANSWER DOWNLOAD EXAMIANS APP
