(2) 2.2 m Q6 A load of P = 85 kN is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 100 GPa, a = 16.9 10C] rods, and a solid / steel [E = 200 GPa, a = 11.9 10 °C] rod, as shown = , / in Fig. P5.54. The bronze rods (1) each have a diameter of 20 mm and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 14 mm. The bars are unstressed when the structure is assembled. After the temperature of the structure has been increased by 45°C. determine: (a) the normal stresses in the bronze and steel rods. (b) the normal strains in the bronze and steel rods. (c) the downward deflection of rigid bar ABC. B. Fig. P5.54
