Tension/compression in curved truss? (Diagram attached)

[Smilemore]

In the diagram, are the tension/compression labels in the correct position? The curve shown continues into a full circle, with the load pulling inwards from the cables shown

Who can say? It is statically indeterminate.

Possibly you want to answer the more specific and difficult question:

"Suppose that the curved truss is put in place with all members relaxed. Now the central spokes are tightened uniformly. What is the resulting pattern of stresses on the truss members now?"

Imagine that each of those elements are springs that can be either compressed (shortening) or tensioned (elongating).
What do you think each will tend to do under the load of those cables?
