B. The three bars supported a concrete beam weighing 50 kN. The length of steel is 0.50 m. Based on the given table of the properties of the materials. both materials have a temperature of 20°C. When the beam is placed, the steel and bronze bar temperature is 30°C. Determine the length of the bronze bar so that the load on each steel bar is twice the load on the bronze bar and If the length of the bronze bar will make the steel stress twice the bronze stress Material Dia E (GPa) a (°C/m) (mm) Bronze 4 100 GPa 17.5 x 10-6 Steel 200 GPa 11.6 x 10-6
