The discussion revolves around the analysis of a truss structure, specifically focusing on the relationship between forces in different members of the truss. Participants are examining the implications of certain loads and reactions on the forces within the truss members, particularly the equality of forces F_DB and F_DA.
The discussion contains multiple competing views regarding the influence of vertical loads on horizontal forces in the truss, and it remains unresolved whether the relationship between F_DB and F_DA is correctly understood.
Participants have not fully resolved the implications of the loads and reactions on the forces in the truss members, and there are assumptions about the distribution of forces that have not been explicitly stated.
Its going to be completely dependent on the 2000lb and 1000lb forces at A and B.SteamKing said:Since the reaction Cx = 0, what does this tell you about the horizontal force in member AB?
Those are vertical loads. How can they influence what happens in the horizontal direction?DiamondV said:Its going to be completely dependent on the 2000lb and 1000lb forces at A and B.
I was thinking of it, that they won't have any components in x. Ah. So the entire 2000lb load is distributed along AD. And the entire 1000lb load is distributed along BD and BE.SteamKing said:Those are vertical loads. How can they influence what happens in the horizontal direction?
