For the truss of Problem 8.3, determine the change in member forces caused by a temperature rise of 30°C in the top chord ABD. Take EA = 200 × 103 kN and the coefficient of thermal expansion is αT = 10 × 10–6/°C for all members. Use the force method.

Problem 8.3

Determine the forces in each member of the truss shown using the force method. Assume all members have the same EA.
