3. Boom ABC is supported by a ball- in-socket at A, cable EBCG and cable CD. Here, cable EBCG passes through small frictionless loops at B and C, and B is at the center of the ABC boom. Neglect the weight of boom ABC. Use the vector formulation to determine the tension force in cable EBCG and the tension force in cable CD. (Hint: the tension force magnitude in cable EBCG is the same throughout the cable. Cable CD is another cable. Think very carefully about what to be taken as the free body, which is not very straightforward, e.g., it is NOT good to take boom ABC as the free body.) 12m x 16m 7.5m B 12m 30 N 20m 9m
