Which chord carries tension and which carries compression depends on the path of the overall loading to the truss. The masses on the truss are commonly inside a downward path, but could transform upward all through extreme wind.
The figures cited on this page are the actual compression and tension ratings of a truss that has been modeled that has a put together dead, Reside, and snow load of forty lb. for each sq. ft. They illustrate the push-pull associations of all the truss associates.
