An externally applied load P of 26 kN is applied to a steel truss as shown below. The cross-sectional area of truss member EF is 2,840 mm2. Dimension "X" is 4 m. Dimension "Y" is 8 m and dimension "Z" is 8 m. Approximate the total decrease in length, in mm, for truss member EF due to the applied loads shown and a temperature drop of 38 oC. If necessary, use Appendix G for any mechanical properties of steel that...
