A sailor is being rescued using a boatswain's chair that is suspended from a pulley that can roll freely on the support cable ACB and is pulled at a constant speed by cable CD. Knowing that alpha = 30 degree and beta = 10degree and that the combined weight of the boatswain's chair and the sailor is 900 N, determine the tension (a) in the support cable ACB, (b) in the traction cable CD.
