•6–5. Assume that each member of the truss is made of steel 2P
having a mass per length of 4 kg/m. Set P = 0, determine the
force in each member, and indicate if the members are in P P
tension or compression. Neglect the weight of the gusset plates

the weight of each member can be represented as a vertical
force, half of which is applied at the end of each member.
