Question: Find the internal forces ( tension or compression ) for all planar truss members when a load of weight W is hung from the two

Find the internal forces (tension or compression) for all planar truss members when a load of weight W is hung from the two middle joints described in (5) above. Assume that this load is distributed evenly between the two middle joints (1/2 W on each plane truss). You may use symmetry arguments. Each internal force should be specified as a function of the applied load W. The bridge is symetrical.
