3) The rigid horizontal bar AB is supported by three vertical rods as shown in the figure and carries the load of 110 kN . The system is stress free before the load is applied. After the load was applied, the temperature of all wires is raised by 20°C. Use a = 12x10-6/°C for steel, a = 18x10-6/°C for copper and a = 20x10-6/°C_for brass. Neglecting %3D the weight of the bar AB, determine the location of the 110 kN force in order that AB remains horizontal. yus brass bar: copper bar: A=195mm? steel bar: A=130mm? A=325mm?
