The method will give you a taste of how the finite-element-method (FEM) works for the solution of problems in solid mechanics. You have learned how to solve a truss Problem 414 Truss by Method of Joints. Problem 414 Determine the force in members AB, BD, and CD of the truss shown in Fig. P-414. Also solve for the force on members FH, DF, and DG.

The most efficient way to solve these problems is to use the Displacement Method. Unless otherwise stated, all of the trusses in this group are stress-free when they are initially assembled. The three truss members in Fig. P3.10-13 allhave cross-sectional area A and modulus of elasticity E. A horizontal load P is applied to the truss at joint A. Truss layout optimization problems with global stability constraints are nonlinear and nonconvex and hence very challenging to solve, particularly when problems become large.

Since truss members are subjected to only tensile or compressive forces along their length, the internal forces at the cut members

The truss frames are generally lighter in weight than the typical beam-column framing system and thus provide a cost savings in material. In addition, due to the high stiffness of the truss, truss frame structures typically can span longer distances and therefore provide for larger open floor areas free of interior support columns found in Chapter 7 Trusses, Frames, and Machines. 2 MEM202 Engineering Mechanics - Statics MEM 7.2 Plane Trusses Before this chapter In this chapter F1 F2 R1 R2 F1 F2 R1 R2 Determine the reactions, R1 An actual riveted truss joint, which transmits both forces and moments among connecting members
