Problem 2 A stake is being pulled out of the ground by means of two ropes as shown. Knowing that a = 30, determine (a) the magnitude of the force P so that the resultant force exerted on the stake is vertical, (b) the corresponding magnitude of the resultant. A telephone cable is clamped at A to the pole AB. Knowing that the tension in the right- hand portion of the cable is T2 = 1000 lb, determine (a) the required tension T1 in the left-hand portion if the resultant R of the forces exerted by the cable at A is to be vertical, (b) the corresponding magnitude of R
