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 25 N 30 N 35 N 40 N 25 N 30 N 35 N 40 N 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 3/2 8/5 5/8 2/3 3/2 8/5 5/8 2/3 ANSWER DOWNLOAD EXAMIANS APP
