A compound steel column consists of two square concrete segments is shown in Figure Q4(b). Segment 1 has 100 mm edges and segment 2 has 150 mm edges. The column is subjected to torques of TB 8 kNm and Tc 12 kNm to act in the direction given in Figure Q4(b). Take Gsteel = 81GPa. = (i) Determine maximum shear stress and angle of twist at point C. (ii) (7 marks) In your opinion, what shapes of cross section that prone to torsional bucking. Provide your judgements. (5 marks)
