2.31. The curved rigid bar ADB is joined to the two elastic bars OA and OBas shown in Fig. 2-48. For additional strength, it is desired to join bar OCto ADB at the midpoint D. However, through a manufacturing error OCis fabricated 1.8 mm too short. Determine the initial stresses in these threebars when point C is mechanically forced to D and these two pointspinned together. The area of each outer bar is three times that of thecentral bar, and for all bars E = 200 GPa.Ans. Outer bars 43.6 MPa, central bar 75.5 MPa1 m,30°30°DIm
