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

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?
