In summary, the conversation discusses the tension/compression labels in a diagram and the resulting pattern of stresses on truss members when the central spokes are tightened. The question remains unanswered as it is a complex and specific scenario.

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?
 

FAQ: Tension/compression in curved truss? (Diagram attached)

What is tension and compression in a curved truss?

Tension and compression refer to the forces acting on the individual members of a curved truss. Tension is a pulling force that stretches the member, while compression is a pushing force that shortens the member.

How does the curvature of a truss affect tension and compression?

The curvature of a truss affects the distribution of tension and compression forces. In a curved truss, the members on the convex side experience tension, while the members on the concave side experience compression.

What is the significance of tension and compression in a curved truss?

Tension and compression are essential for the stability and strength of a curved truss. They work together to transfer the load from the top of the truss to the supports at the bottom, allowing the truss to withstand external forces.

How do engineers determine the amount of tension and compression in a curved truss?

Engineers use mathematical equations and structural analysis techniques to calculate the amount of tension and compression in each member of a curved truss. They also consider the design load and the properties of the truss materials.

Can tension and compression be present in a single member of a curved truss?

Yes, it is possible for a single member of a curved truss to experience both tension and compression. This occurs when the member is located at the point of maximum curvature, where the forces change direction from tension to compression.
