The rigid beam BC shown in the figure is supported by rods (1) and (2) that have cross-sectional areas of 160 mm² and 320 mm², respectively. For a uniformly distributed load of w- 18 kN/m, determine the normal stress in each rod. Assume L-2.0m and a-1.4 m. The stresses are positive if tensile and negative if compressive.
