Determine the force in each member of the truss. Note the presence of any zero-force members.

Problem Statement Based on Problem 6-17 from the textbook. If the maximum force that any member can support is 8 kN in tension and 6 kN is compression, determine the maximum force P that can be supported at joint D. a=4.3m b=3.0m Unique Values for Each Student: Theta=60 degrees b

1. For the one-dimensional 3 truss-element system shown, determine the nodal displacements and reaction forces using the direct stiffness method. K2 = 60 lb/in KI= 50 lb/in K3 = 55 lb/in Node 4 F = 60 lbs. Node 3 Node 1 Node 2 +X 2. For the one-dimensional 4 truss-element system shown, determine the nodal displacements and reaction forces using the direct stiffness method. K2=35 lb/in F=80 lbs Kı=35 lb/in K3=25 lb/in K4=30 Ib/in +X 3. For the one-dimensional 4 truss-element system shown, determine the nodal displacements and reaction forces using the direct stiffness method. K3=45 lb/in F=75 lbs KI=25 lb/in K2=35 lb/in K=30 lb/in to +X

Fishing line with a tensile strength of 25 lbs is used at B to fasten 2 members together as shown. Find the maximum force F that can be supported, given:L1 = 2 in, L2 = 4 in L3 = 6 in, L4 = 5 in

Determine the force in each member of the loaded truss. The forces are positive if in tension, negative if in compression. Assume F1 = 4070 Ilb, F2 = 4680 lb, a = 4.3 ft, b = 6.3 ft, c = 2.4 ft, and d= 3.5 ft. E Answers: AB = ! Ib AE = ! Ib BC = Ib BD = Ib BE = ! Ib CD = Ib DE = i Ib

Determine the force in each member of the space truss given F-3 kN. Use positive to indicate tension and negative to indicate compression. Z D FAB= 5.35 FAC = 1.25 FAD = 1.25 FBC= 3.08 FBD = 3.08 FBE = 4 3 m E 2 m 3 m 4 m. x kN X KN X KN x kN x kN X KN B 5 m A F y

Determine the force in member CG. The force is positive if in tension, negative if in compression.Assume F1 = 9 kips, F2 = 12 kips, F3 = 11 kips.
