Plane and Space Trusses

In civil engineering, a truss is the most important structure that forms the most fundamental member of any building structure and commercial complexes. Trusses are composed of individual members or links that are interconnected by suitable joints, such as rivets, welds, or bolts, and nuts. In trusses, the interconnection leads to the formation of a series of triangles joined together such that all the triangular members behave as a single rigid body. In a simple truss, three members are connected to form a truss member. In trusses, the force always acts at the joints or the interconnection between the individual members.

Question

1.20 Calculate the truss's smallest allowable cross-sectional areas of members CE, BE,
and EF. In tension, the working stresses are 20 ksi, while in compression, they are 14
ksi. (In compression, the working stress is lower to lessen the risk of buckling.)
