The lower ends of the three bars in the figure are the same level before the rigid homogeneous W=100 kN block is attached. The properties of the bars are shown in the table. The temperature of the bars is then increased by 80°C. The block is assumed to remain horizontal after all deformations have occured. a.) Which of the following most nearly gives the temperature rise to cause all of the applied loads to be supported by the steel rods? b.) Which of the following most nearly gives the stress developed in the bronze bar? c.) Which of the following most nearly gives the stress developed in the steel bar?
