Please solve step by step clearly how to answer these two questions shown below. The given parameters for question 1 are provided as seen stating that B=D(mm)=407 and P= 3040kN. For question two e1=433.4 mm and e2 is equal to 327.84 mm.

Question 1: A composite column consists of a square outer steel tube, inner Universal Column (UC) section with designation 250 UC 89.5, and infilled with normal strength concrete as shown in Figure Q4. The composite column is subjected to P kN axial load, applied at the top of the column through a rigid plate. The column is fixed at the base. Calculate the axial forces and axial stresses of the three elements i.e. outer steel tube, infilled concrete and inner UC section using the principle of compatibility. Discuss if the three elements have failed under the axial load. The geometrical and material properties of the elements are given as follows: Gross area of UC section = 1 1400 mm ii. Elastic modulus of concrete, Ec - 32 GPa iii. Elastic modulus of steel tube and UC section, Es - 205 GPa, iv . Concrete compressive strength, fou - 25 MPa and v. Yield strength of steel tube and UC section, fy = 320 MPa.
