A force distribution system consisting of four rods in series connection are supported by two fixed supports, one at each end. Each rod experiences both thermal expansion and an external axial force applied at the junctions between the rods. During an operation, consider the following: • The rods are subjected to a temperature rise of 50 K. • At the junction between the first two rods, there is an external concentrated force of 50 kN, and 100 kN at the junction between the next two rods.

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
