I need some help with this spring assemblage question. In the
image below the nodes are actually reorganized in the question in
the order of 1-5-4-3-2. Now Knowing that I have to a) write the
global stiffness matrix for it b) if nodes 1 and 2 are fixed and a
force P is at node 4 what is the nodal displacement, c) I need to
find the reactions at 1 and 5 and finally d) I need to find the
internal forces for node 1-5 and nodes 3-2 and determine whether or
not in compression or tension

Figure Q5(a) shows a plane truss supported by a horizontal spring at the top node. The truss members are of a solid circular cross section having a diameter of 20 mm and an elastic modulus (E) of 80 GPa (10° N/m2). The spring has a stiffness constant of k-2000 kN/m. A point load of 15 kN is applied at the top node. The direction of the load is indicated in the figure. The code numbers for elements, nodes, DOFS, and...
