I took a mock test where I was asked to show the directions of forces along the rods (I was given a multiple choice, and the each rod had one force along it in every choice), and much to my chagrin I failed, so much so that I begun to question the sanity of the questioner. Are there any force acting along the rods, or am I not a total failure?

Tension acts up both of the two rods. W must be balanced by the vertical components of the tensions in the rods.

I cant see how force would act only on one of the rods, the vertical components of both the tension in the rods and the weight must all add up to zero, assuming its in equilibrium.

I would have thought that the bottom rod would be in compression? The top rod is definitely in tension.
Forces "along the rods" - not sure what you mean. The rods have internal forces
