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 711 N mm 511 N mm 411 N mm 611 N mm 711 N mm 511 N mm 411 N mm 611 N mm ANSWER DOWNLOAD EXAMIANS APP

Theory of Structures A short column (30 cm × 20 cm) carries a load P 1 at 4 cm on one side and another load P2at 8 cm on the other side along a principal section parallel to longer dimension. If the extreme intensity on either side is same, the ratio of P1 to P2 will be 2/3 5/8 3/2 8/5 2/3 5/8 3/2 8/5 ANSWER DOWNLOAD EXAMIANS APP
