A Question 2 A steel beam extending beyond is upheld at points B and D, as depicted in Figure Q2(a). The beam's cross-sectional area is illustrated in Figure Q2(b). Answer the following questions: i. Determine the neutral axis () and second moment of inertia (INA) for the cross section of the beam. iii. ii. (4 marks) Calculate the maximum bending stress (max) for tensile and compression in the beam and identify the location, measured from point A. (5 marks) If the beam is replaced with a 150 mm x 150 mm solid square beam of the same material, state whether the bending stress will increase or decrease? Justify your answer. 2 m Be e 10 kN (1 mark) 150 mm 30 mm T 120 mm 1 m 1 m k 90 mm Cross Section e-e Overhanging Beam ABCD (a) (b)
