Bronze 2 m Steel 1.0 m A H0.6ml-1.0 m- -0.8 m→ 50 kN The figure shows a rigid bar that is supported by a pin at A and two rods, one made of steel and the other of bronze. Neglecting the weight of the bar, compute the stress in each rod caused by the 50-kN load, using the following data: Steel Bronze Area (mm?) E (GPa) 600 300 200 83
