Fig. 2 2. (20 Points) Two rods, AC and AD, are attached at A to column AB. Knowing that the force in the right-hand rod is F2=100N, and that the inclination angles of the rods are 1=30 and 2=20, determine (a) the force F1 in the left-hand rod if the resultant of the forces exerted by the rods on the column is to be vertical, (b) the corresponding magnitude of the resultant
