PLEASE ANSWER WITH COMPLETE SOLUTIONS FOR A RATE

consists of a steel cylinder (E = 200 GPa, A = 150 mm2, a = 12 um/m.°C), an
aluminum alloy cylinder (E = 70 GPa, A = 230 mm2, a = 23 um/m-°C), and a hollow bronze tube
(E = 100 GPa, A = 190 mm2, a = 18 um/m-°C) welded to the rigid bar at points A, B, and C,
respectively. Initially, the system is stress-free. When the assembly is heated by 45°C, determine
the normal stress (in MPa) in the bronze tube and the horizontal distance (in m) with reference to
%3D
point A where the rigid bar tilts. Neglect the weight of the members.
