2.11 A barge is pulled by two tug boats. To move the barge along in the water properly, the tug boats must exert a resultant force of 5000 lb along the direction of motion of the barge. (a) First determine, the tension in cach rope if the position of tug B is such that = 45. Second, suppose that tug B can move anywhere such that 0 < < 90. Determine the angle 3 where the tension in tug B's rope is (b) maximum and again where it has a (c) minimum value still maintaining the resultant of 5000 lb along the x direction on tug A.
