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