The rigid bar EBC is supported by two links AB and CD as shown in Figure 1. The Link AB is made of aluminum (E = 70 GPa) and the link CD is made of steel (E = 200 GPa). Both links have a Width = 30 mm x thickness= 5 mm rectangular cross-section. Each of the four pins A, B, C and D has a 7 mm diameter.
