Learning Goal: To analyze the forces within space truss members and the reaction forces that act on space trusses. A space truss is a stable trree-dimensional structure that consists of members joined at their ends. If tho exdernal looding is applied at the joints, and the joints are ball. and-sockot connections, the members of a space triss Part A. Review may be treated as two-forco membors. A space truss is subjected to a load of E={140i−400k} th (Figure 1} Throe ball-andsocket joints at C. E, and G support the space truss. If Fr​ a 140Ib,Fc​=400lb in the negotive z dicoction, and d=4.00ft, what is the magnitude of the force in member AC ? Figure Indicale a tensile force as a positive valuo and a compressive force as a negative value. Express your answer numerically to three significant figures in pounds.
