All truss members in the truss shown are made of the same material and are of the same cross-sectional area. The failure normal tensile stress for the material is 16ksi, and the failure compressive normal stress is 10 ksi. A factor of safety, FS, of 1.6 is to be applied. The internal forces in each member can be computed using statics. As a hint, it was predetermined that the maximum forces occur at members DE and AD. Determine the following by using 4 decimal places: * Magnitude and type of axial force in member DE. * Magnitude and type of axial force in member AD. * The required area in in2 for truss member DE. * The required area in in2 for truss member AD * What is the minimum required cross-sectional area in in2 for all the members if they are to be of the same size?
