(a) determine the nodal displacements;

(b) hence, determine the nodal reactions, representing these on a sketch of the deformed geometry. Show that both force and moment equilibrium is satisfied.

Solution

(a) Figure 9.37 shows suitable node, dof. and element labelling. Lack of symmetry prevents any advantage being taken to reduce the calculations. There are no redundant members.

Employing two beam finite elements, (which is the least number in this case), both elements will have the same E/L, i.e.
