Download Solution PDFConcept:
To identify the zero force members in truss, the following rules are required to be used:
1. If at a joint three members are meeting, two of which are collinear then force in third member is zero provide that no external load is acting on joint.
2. If two non-collinear members are meeting at joint and no external load is acting on that joint, then force in both members is zero.
Calculation:
Joint D:
Member DC and DE are non-collinear and No external load an joint D.
So
Joint E:
∑Fy = 0
⇒ FEF = 0
∑ Fx = 0
Joint C:
FE2 = + 5 kN (Tensile)
FCI = 0 Rule (2)
FCB = 0 Rule (2)
Zero force members
Area DE, DC, EF, CI, CB
