Question

Week 8, Question 1: For the truss shown in the following figure, the temperature of member BC is raised by 50 °C, and member BD is raised by 80 °C. EA= 300000 N for all members and a=1/75000 1/°C. Use the stiffness method to do the following: А. 5 m h5m_ Part 1. Calculate the displacements at the joints: a) Az = mm b) Ay = mm c) B2 = mm d) By = mm e) C mm
For the truss shown in the following figure, the temperature of member BC is raised by 50 ∘C, and member BD is raised by 80 ∘C. EA= 300000 N for all members and α= 1/75000 1/∘C. Use the stiffness method to do the following:
