Describe the Assembly of atoms forming the basic clay mineral sheet alumina octahedron .
steel A aluminum 2 m B 2 m 9 m bronze с 3 m The assembly shown consists of a steel cylinder (E = 200 GPa, A = 150 mm2,= 12 µm/m-°C), an aluminum alloy cylinder (E = 70 GPa, A = 230 mm2, = 23 µm/m °C), and a hollow bronze tube (E = 100 GPa, A = 190 mm2, = 18 μm/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 point A where the rigid bar tilts. Neglect the weight of the members. The answer should be: Obr = 8.9507 MPa, C, d = 4.6625 m
