Set up and solve for the displacements at the nodes and for the forces transmitted by each of the

elements. Follow the following sequence of steps:

• Number the nodes

• Determine AE/L for each element

• Determine the 4x4 elemental stiffness Ke for each element

• Expand each Ke to the global level and add to the global stiffness matrix

• Form the global load matrix

• Enforce the constraints

• Solve the equations

• Calculate the forces transmitted in each member

• Verify nodal equilibrium and calculate reactions

All areas = 2 in2, All E’s = 30x106 psi
