Transcribed Image Text: Zero-Force Members are structural members that support No loading but aid in the stability of the truss.
Tips on getting the zero-force members:
1. there is no external load or reaction at that joint
2. Insufficient structural members to satisfy or “balance” the system: Summation of forces along the horizontal
and vertical
3. two of the members are collinear
As shown in the figure, structural members of zero-force members can be noticed through observation.

At a glance, it can be inferred that the member FG and FE are zero force members, because:
First, there is no external load applied on the joint
Secondly, taking the Joint F, if Summation of Forces along horizontal = 0 is executed, only the member FG has
the horizontal component, or the “ability” to “balance” the system, and if Summation of Forces
= 0 is executed, the member FE has the vertical component, or the “ability” to “balance” the system only.
along vertical
Aside from members FG and FE, through observation, determine the other zero-force members.
