For the plane truss with inclined support shown, use structural finite element method to determine the nodal displacements at node 1. Use E-70 GPa and A = 2000 mm² for all elements. Define [et] and use it. so that the resulting boundary conditions on the displacement is not in the global x-y directions but is in the "local" x'-y directions. Ans.: u₂ = 49.8 mm, u₂y = 10.7 mm 1000 KN 38 50 8 m 777777 10 m For the plane truss with inclined support shown, use structural finite element method to determine the nodal displacements at node 1.
