E.g.-Test the statically determinacy of the pin jointed trusses shown in below given figure:- Solution: The truss has five members and four joints. KN371.1 0m10cosm5kN1m10kN1.439375.0 m8 m5 tan GH G I GI cfgh kN371.1 zero-forcemembers: If a joint has only two non-collinear members and there is no external load or support reaction at that joint, then those two members are zero-force members. Solution: Take the entire truss as a free body. The loads act only at the joints,. Zero-force members can be removed (as shown in the figure) when analyzing the truss. 10 P a g e There is one unknown member force at joint. Trusses that are supported at more than two positions are said to be statically indeterminate, and the application of Newton's Laws alone is not sufficient to determine the member forces. 2.space frame truss: A space frame truss is a three-dimensional framework of members pinned at their ends.
