The rigid bar of negligible weight is supported as shown in the figure. If W = 80 kN, compute the temperature change of the assembly that will cause a ten- sile stress of 50 MPa in the steel rod. Use the following data: Steel rod Bronze rod Steel 1.5 m 1.0 m 2.5 m W A (mm) 300 1400 Bronze 3 m 1.5 m - a (/C) 11.7 x 10-6 18.9 x 10-6 E (GPa) 200 83 The rigid bar of negligible weight is supported as shown in the figure.
