Problem # 5: The horizontal member shown in the figure is loaded by 25 kN at E. It is supported by steel
connector AB (E = 200 GPa, A= 620 mm² ) and aluminum connector CD (E = 70 GPa, A = 530 mm² ).
Determine the deformation incurred by connectors AB and CD. Also, calculate the vertical displacement of E.
