The boom 4C is supported at 4 by a ball-and-socket joint and by two cables BDC and CE (figure 3). Cables BDC is continuous and passes over a frictionless pulley at D. Calculate the tension in the cables and the reactions at 4 if a crate, having a weight of 80 N, is suspended from the boom. Note: For a ball and socket joint, there are three force reaction (A, Ay, A:). 30 m. 6 m 4 m 8 m Figure 3
