22. A truss is a structure made of mem- bers joined at their ends. For the truss shown in the figure, the forces in the 11 members are determined by solv- ing the following system of 11 equa- tions: 36 ft 1200 lb 800 lb 30 ft Ⓒ Ficos 50° +F₂=0, Fisin 50° - 400=0, -F₂ +F6=0 -Ficos 50° +F4 + F5cos 41° =0, F₁sin 50° +F3 + F5sin 41° - 800 = 0, -F5cos 41°-F6+F10 =0, Fssin 41° + F7-1200 = 0, 42 ft 400 lb 48 ft -F4+F8 + Focos 37° =0,-F₁-Fosin 37° = 0, -Focos 37°-F10-4933=0, Fosin 37° + F11 = 0 Write the equations in matrix form and use MATLAB to determine the forces in the members. A positive force means tensile force and a negative force means compressive force. Display the results in a table where the first column displays the member number and the second column displays the corresponding force.
