SITUATION 5: The rigid bar of negligible weight is supported as shown in the figure. A (mm2) α (/⁰C) E (GPa) Steel rod 300 11.7 x 10-6 200 Bronze rod 1400 18.9 x 10-6 83 1. If W = 80 kN, compute the temperature change of the assembly that will cause a tensile stress of 50 MPa in the steel rod A. decrease by 22.7⁰C C. decrease by 18.4⁰C B. increase by 22.7⁰C D. increase by 18.4⁰C 2. Find the stress (MPa) in steel rod if the temperature rises 20⁰C after a load W = 120 kN is applied. A. 50.8 C. 0.0266 B. 65.3 D. 52.1 3. Find the stress (MPa) in bronze rod if the temperature rises 20⁰C after a load W = 120 kN is applied. A. 50.8 C. 62.9 B. 65.3 D. 52.1 Thanks for watching!
