Remember the Four-Step plan:

1. Equilibrium: Draw an FBD of connector C and write down the equilibrium equation from this FBD.
2. Force/elongation equations: Write down the force/elongation equation for each member:  e_i = F_iL_i/EA_i + αΔT_iL_i.
3. Compatibility equations:  Write down the elongation/displacement compatibility equation relating the elongations of rods (1) and (2).
4. Solve: Solve the equations generated in Steps 1-3 for the loads carried in the two rods and the displacement of connector C.
