A rigid bar of negligible weight is supported as shown i the figure. If W = 80 KN, compute the temperature change that will cause the stress in the steel rod to be 55 MPa. Assume the coefficients of linear expansion are 11.7 µm/(m.°C) for steel and 18.9 μm/ (m.°C) for bronze. Figure P-271 and P-272 Bronze L = 3 m Steel A = 1300 mm² E = 83 GPa L = 1.5 m A = 320 mm² E 200 GPa = -1m- 4 m 2 m W
