Alpha [X]²;1288819 said: Yes, the numbers on the members in the diagram. I assume the numbers represent the forces in the members, and the colors represent compression/tension. As I said, you can calculate every force by looking at every node separately. Imagine you "cut out" the leftmost node.How To Calculate Roof Truss Strength . Trusses are created from wooden members. Members are pieces of wood that are connected together with metal plates to form triangles. The locations where the pieces meet are called "nodes." In order for roof trusses to create a stable load distribution, it is important that the truss include support nodes.Trusses typically follow a pretty general and common structure, made up of various components. Below is a list of the relevant parts of a truss: (1) Top Chord – the beam of a truss spanning the length of the truss. (2) Bottom Chord – the bottom beam spanning the length of the truss. (3) Web – these are the internal members of a truss.Question: 5.9 Calculate the forces in all members of the trusses shown using the method of joints.
