The two-bar structure shown is pinned at A, B, and C. A sign weighing 20 kN is suspended from bar BC at points D and E, which are located at 0.8 m and 0.4 m, respectively, from the ends of the bar BC. If member AB is a steel pipe with inside diameter 20 mm, determine the smallest permissible outer diameter of the member if the working stress in steel is not to exceed 140 MPa.
