Also indicate all zero-force members. Check all that apply. Check all that apply. Also indicate all zero-force members. Check all that apply. Solution DF and CF Only. Explanation: The chances of zero members can be DF, CF, GC, BH and CH. Starting from DF: We know DF is zero member as there is no load in the joint D and DF joins a straight member CE....Likewise if DF is zero, then CF also becomes a zero member (in the same sense as explained for DF)...But this is not the case for BH as there is a load at joint B..CH also cannot be a zero member as it is not connected to just a straight member (instead BH also exist).....Now coming to GC, GC is not a zero member as there is a load acting at joint G. .
