A steel profile (S355) is welded together from two flat steels as indicated in the sketch. Modulus of elasticity to steel is 2 x 105 N/mm². The welds must be neglected in the calculations. 160 * y x [mm] *Ж 14 Ж y₁ 14 286 Σ(x*A₁) a) Calculate the location of the center of grabity axis x. Using the equiation: x = A wwwww b) Calculate the first moment Sy of area of the cross section above the center of gravity axis x. c) Calculate second moment of area ly.
