The tower for a transmission line is modeled by the truss shown. The crossed members in the center sections of the truss may be assumed to be capable of supporting tension only. For the loads of 1.8 kN applied in the vertical plane, compute the forces induced in members AB, DB, and CD. 5 panels at 3 m D J I E A 3 m G B F 1.8 kN C (1.8 kN 15 3 m 15 K 3 m 5 m
