1) A Warren bridge truss is shown to the below. (a) Determine the support reactions at A and K. (b) Determine the force in members CE, DE, and DF using method of joints. (c) Determine the force in members CE, DE, and DF using method of sections. (Note: A is a roller and K is a pin.) Ans: Ay 8400 lb (1), Kx = 0, K, = 3600 lb (↑), FCE = 8000 lb (T), FDE= 2600 lb (T), = 9000 lb (C). [Intermediate answers for method of joints: FAB = 9100 lb (C), FAC = 3500 lb (T), FBC = 9100 lb (T), FBD = 7000 lb (C), FcD = 2600 lb (C)] %3D %3D %3D FDF %3D %3D %3D %3D
