A truss is a structure made of members
joined at their ends. For the truss
shown in the figure, the forces in the
nine members are determined by solv-
ing the following system of nine equa-
tions:
MAX

1500 lb
F₂+ cos(48.81°)F₁ = 0
42 n

48 ft
F6+ cos(48.81°)F₁-F₂ = 0,
sin (48.81°)F, +F3 = 0 -cos (48.81°)F₁+F₁ = 0
-sin (48.81°)F₁+F3 = 1800, -F- cos(48.81°)F, = 1200,
-F₁-sin (48.81°)F,- sin(45°)F, = 0, sin (45°) F, = 1500,
- cos(45°)F,-Fg = 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 correspond-
ing force.
