Cranes, such as this one that is removing the crane that was involved in the brick refacing of krannert center, are comprised of truss-like structures to achive high strength and low weight. let us model the illustrated crane boom as a planar truss that is subjected to the tension load t t. given the following: t = t=700 kn l = 2 l=2 m θ = 5 o θ=5o α = 20 o α=20o determine force f a b fab in kn in the blue member a b ab¯. matlab input: t = 700; l = 2; theta = 5; alpha = 20;
