The steel beam ABCD shown is simply supported at A and supported at B and D by steel cables, each having an effective diameter of 12 mm. The second area moment of the beam is I = 8(105) mm4. A force of 20 kN is applied at point C. Using procedure 2 of Sec. 4€“10 determine the stresses in the cables and the deflections of B, C, and D. For steel, let E = 209 GPa.
