b) If the centric 25 kN force is removed and the whole system (I.e. the post and the tube) is heated so that its temperature increases by 70°C, determine the normal stress (1) in the aluminium post. (i) in the brass tube. Coefficients of thermal expansion for brass and aluminium are 20.9x109/°C and 23.9 106/°C, respectively, (13 marks) 25 KN B 250 mm 75 mm 50 mm
