A steel section has the following properties: A = 0.012 m^2 rt = 0.053m tf = 0.016m Sx = 0.00208 m^3 d=0.210m Fy=248MPa The 5m Beam is subjected to an axial tensile load of 20 kN and a uniformly distributed lateral load of 15 kN/m. a. Compute the axial tensile stress if axial load only existed. b. Compute the axial tensile stress if bending only existed. c. Compute value of both axial and bending moment interaction value.

B. (i). A rectangular concrete beam 250 mm wide × 475 mm overall depth is simply supported over a 7.0 m span. Using the data given, check the suitability of the beam with respect to deflection. Data:Characteristic strength of concrete (fcu) 40 N/mm2Characteristic strength of main steel (fy) 460 N/mm2Design ultimate bending moment at mid-span (M) 150.0 kNmAssume the distance to the centre of the main steel from the tension face is 50 mm (ii). Analyse above mentioned simply supported beam using solid work software to justify your choice. Mention assumptions where necessary.
