I need MathLab code with step by step comment i will give thumbs up for work thanks:)

148 ft A truss is a structure made of members 600 lb joined at their ends. For the truss shown in the figure, the forces in the nine mem- 48 ft bers are determined by solving the fol- 1800 lb lowing system of nine equations. cos (45)Fi + F = 0 14800 lb -F3 - sin(45F) = 0 - F2 + sin(45)F3 +F6 = 0 -cos(48.81)F3-F4 + Fs = 0, -sin(48.81F3-F, = 600 - sin(48.81F, = 1800, -Fs-cos(48.81F, = 0, F,+ sin(48.81F, = 4800, cos(48.81F,-F6 = 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. Submit a Matlab script named as P22_namestudent. (no written document) The variation of vapor pressure p (in units of mm Hg) of benzene with temperature in the range 0.05223a of 0 STS 42 C can be modeled with the equation: log, p=b- where a= 34172 and b - 7.9622 are material constants and Tis absolute temperature (K). Write a program in a script file that calculates the pressure for various temperatures. The program should create a vector o temperatures from T= 0 C to T = 42 C with increments of 2 degrees, and display a two-column table p and T, where the first column temperatures in Celsius, and the second column the corresponding in mm Hg (include units in the table). Save the data in a file using fprintf command. Submit a Matlab script named as P18_namestudent. (no written document)
