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: to be applied. The internal forces in each member can be computed using statics. As hint, it was predetermined that the maximu forces occur at members DE and AD. Determine the following by using 4 decima places:

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?
