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 611 N mm 411 N mm 511 N mm 711 N mm 611 N mm 411 N mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported rolled steel joist 8 m long carries a uniformly distributed load over it span so that the maximum bending stress is 75 N/mm². If the slope at the ends is 0.005 radian and the value of E = 0.2 × 106 N/mm², the depth of the joist, is 300 mm 250 mm 200 mm 400 mm 300 mm 250 mm 200 mm 400 mm ANSWER DOWNLOAD EXAMIANS APP
