4.32 The axial force F, in each of the 13-member pin- connected truss, shown in the figure, can be calculated by solving the following system of 13 equations: F2+0.707F10, F3-0.707 F-2000 = 0 0.7071F+F4+ 6229 = 0, -F4-0.753 FS-6000,-F3-0.659 F5 + F₁ = 0 0.753 F + F = 0, -F2+0.659 F,+F6-0 -F6+0.659F9+ F10 = 0 8 m 1800 N 600 N 800 N 600 N © (3) © A 7m 7m 8m 2000 N -F-0.753 F9-800-0, -F7-0.659 F, + F11 - 0 = 0.753 F,+F12-24290, -F10+ 0.707F13 = 0 -F12-0.7071F13-600 = 0 (a) Solve the system of equations using the user-defined function Gauss Pivot Large developed in Problem 4.21. (b) Solve the system of equations using Gauss-Seidel iteration. Does the solution converge for a starting (guess) vector whose elements are all zero? (c) Solve the system of equations using MATLAB's left division operation.
