A rigid horizontal bar of negligible mass is connected to two rods as shown in Fig. If the system is initially stress-free. Calculate the temperature change that will cause a tensile stress of 80 MPa in the brass rod. Assume that both rods are subjected to the change in temperature. Brass L=2 m A = 1200 mm? E= 100 GPa a= 18.7 um/(mC) 3 m - 2 m - Соpper L= 3m A = 1500 mm E = 120 GPa a = 16.8 um/(m"C)
