Problem 4. A sailor is being rescued using a boatswain's chair that is suspended from a frictionless pulley that can roll on the support cable ACB and is pulled at a constant speed by cable CD. Knowing that a = 30° and B = 10° and that the combined weight of the boatswain's chair and the sailor is 250 lb, determine the tension in the support cable ACB. (Hint: tension in CD will not be equal to the other rope.) D
