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
