Determine the components of reaction at the ball-and-socket joint A and the tension in each cable necessary for equilibruim of the rod.

II. Draw (approximately) the moment diagram for column AGF of the portal. Assume all the members of the truss to be pin connected at their ends. The columns are fixed at A and B. Also determine the force in all the truss members. -2 m- 2 m - D 4 kN 1.5 m 8 kN 5 m II. a. Use the portal method and determine (approximately) the reactions at supports A, B, C, and D. b. Use the cantilever method and determine (approximately) the reactions at supports A, B, C, and D. All columns have the same cross-sectional area. K L 9 kN 4 m F H 12 kN 4 m A В D 5 m 5 m 5 m

Find the internal forces in all the cables. The applied loads are P1 = 6 kN and P2= 7 kN. E A 2 m D 3 m В 8 kN P1 4 m 5 m 4 m 1.5 m
