2. For a structure in static equilibrium, the sum of the forces and moments are both zero, which holds for each individual member as well as the entire structure. The force balances for a system of seven members and five joints are provided by 3 + F2 = 0, (2) [(F1-F3) = 0, (4) (3) 2 F V3 (Fs - F7)] (5) F2 - F6 F) = 0, (6) (F3 + Fs) = 3, (7) F: + = 0, V3 F 3 (Fs + Ft) = 0, (9) F6 + = 0, F = , 2) MARE "=- 2 v ( F. + F) = 0, [Fs+ 3 )] - -- 2 2 (10) 2 2 Arrange the system of equations as Ax = b, with x = [F1 F2 F3 F F F Fy)". Obtain the ranks of A and aug(A), aug(A) = (A b), and comment on whether the system of equations has one or more solutions. Obtain the solution using Matlab
