Example 2: Rigid rod supported by BDE, AB and CD. AB is made of aluminum (E = 70 GPa) and its area is 500 mm2, CD is made of steel (E = 200 GPa) and its area is 600mm2. Find a) the displacement at B b) the displacement at D c) the displacement at E due to the 30kN force acting at the end of E. Solution: We find the forces from the free body diagram of BDE.
