For the truss structure shown: 1) set-up element stiffness matrices for each element, 2) assemble global stiffness matrix equations, 3) apply boundary conditions, 4) solve for unknown displacements, 5) solve for reactions and stresses in each element. Given are: E = 10Msi, v = 0.3, A₁ = A3 = 0.5in² and A₂=A4 = 0.25in². 500lbf 30in 5 m N 22 12in 12in 12in For the truss structure shown: 1) set-up element stiffness matrices for each element, 2) assemble global stiffness matrix equations, 3) apply boundary conditions, 4) solve for unknown displacements, 5) solve for reactions and stresses in each element.
