For the truss shown in the figure, the forces in the 11 members are determined by solving the following system of 11 equations. 1200 lb 400 lb 30 ft I 42 ft 48 ft F1 cos 500 + F, = 0, F1 sin 500-400 = 0 , -F, cos 500 + F, + FS cos41 = 0, -F, sin 50 + F3-F, sin 41-800 = 0, -F, cos 41-F, + F,o=0, Fs sin 41 + F7-1200 = 0. -F, + F, + F, cos 370-0, -F,-F, sin 37" 0 -r, cos 37"-F,0-4933: 0, Fo sin 37+F110. Rewrite the equations in a matrix format Ax b and write a MATLAB script file named HW4P3 to determine the forces in the members. A positive force means tensile force and a negative force means compressive force. Using the disp function in MATLAB to display the results in a table where the first column displays the member number and the second column displays the corresponding force Whitmice Chapter 4 N.. ptx Whitmire Chapter 4 N... .pptx
