PROBLEM 2.5 Two control rods are attached at Ato lever AB. Using trigonometry and knowing that the force in the left-hand rod is F1=120 N, determine (a) the required force F2in the right-hand rod if the resultant Rof the forces exerted by the rods on the lever is to be vertical, (b) the corresponding magnitude of R
