Click For Summary
The discussion revolves around the correct labeling of tension and compression in a diagram of a curved truss that extends into a full circle. It is noted that the system is statically indeterminate, complicating the analysis. A more specific inquiry is raised regarding the stress patterns on the truss members when the central spokes are uniformly tightened from a relaxed state. Participants are encouraged to visualize the truss members as springs, considering how they would react under the inward load from the cables. Understanding these dynamics is crucial for accurately assessing the structural behavior of the truss.

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?
 

Thread 'Is energy really conserved?'

I built a device designed to brake angular velocity which seems to work based on below, i used a flexible shaft that could bow up and down so i could visually see what was happening for the prototypes. If you spin two wheels in opposite directions each with a magnitude of angular momentum L on a rigid shaft (equal magnitude opposite directions), then rotate the shaft at 90 degrees to the momentum vectors at constant angular velocity omega, then the resulting torques oppose each other...
