Theory of Structures A spring of mean radius 40 mm contains 8 action coils of steel (N = 80000 N/mm²), 4 mm in diameter. The clearance between the coils being 1 mm when unloaded, the minimum compressive load to remove the clearance, is 35 N 25 N 30 N 40 N 35 N 25 N 30 N 40 N 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 611 N mm 411 N mm 711 N mm 511 N mm 611 N mm 411 N mm 711 N mm 511 N mm ANSWER DOWNLOAD EXAMIANS APP
