Question

The members carrying zero force (i.e. zero -force members) in truss shown in the figure, for any load P > 0 with no appreciable deformation of the truss (i.e with no appreciable change in angles between the members), are

• A. BF, DH and GC only
• B. BF, DH, GC, CD and DE only
• C. BF and DH only
• D. BF, DH, GC, FG and GH only

Answer 1

The correct option is B

BF, DH, GC, CD and DE only

The members carrying zero force (i.e. zero -force members) in the given truss are BF, DH, GC, CD and DE only.
