Some basic concepts of engineering analysis In this example we used the direct approach; alternatively we could have used a variational approach. In the variational approach we operate on an extremum formulation: u = strain energy of system W = total potential of the loads Equilibrium equations are obtained from an - 0 (b) ~-1 In the above ...
