For the ropes and force of the river of Prob. 2.46, determine (a) The value of α
Question:
(a) The value of α for which the tension in rope AB is as small as possible,
(b) The corresponding value of the tension.
Problem 2.46: Ropes AB and AC are thrown to a boater whose canoe had capsized. Knowing that α =25° and that the magnitude of the force FR exerted by the river on the boater is 70 lb, determine the tension (a) in rope AB, (b) in rope AC.
