Situation 4 - A load of W = 30 Li L2 kN is lifted through a boom BCD as shown in the Figure AP-4.10. The boom makes an angle of 60° with the vertical. Neglect the weight of the boom and for this w problem, L1 = L2 = 2 m. The pulley at D is frictionless. 10. Determine the angle a. Answer: 30° 11. What is the tension in cable 60° Figure AP-4.10 B AC in kN? Answer: 25.36 kN 12. What is the total reaction at B in kN? Answer: 54.77 kN
