SITUATION. As shown in the figure below, a rigid bar with negligible mass is pinned at O and attached to two vertical rods. Assume that the rods were initially stress-free. Allowable stress in steel is 120 MPa and in bronze is 60 MPa. For this problem, a = 1.8m; b = 1.3m; c= 1.7m. a b C Steel: A=900 mm² E = 200 GPa L=1.5m Bronze: A=1200 mm E=83 GPa L=2.0m What is the ratio of the elongation of steel to bronze? O 0.367 0.433 0.467 0.333
