Truss Bridge Diagram Group projects
This a group project on making a bridge.
Trusses have been used in bridge building since the middle ages. Trusses are made up of a top and bottom chord, diagonals and vertical posts. These are the primary members of the bridge. The top chord of the truss is in compression* ,the bottom chord in tension. * End diagonals are in compression*, interior diagonals can be in either tension* or compression* depending on the truss type and location of the member. Vertical posts are in tension.*
Counter bracing or ties are diagonals, present in certain types of trusses, sometimes in the center panel.
