Summary
Often loads applied to a structure do not depend on the deflections they induce. If there is a dependency, they couple the very forces in equilibrium to the displacements they induce, leading to statical indeterminacy. Solving such problems proceeds by assuming a displacement profile dictated by the characteristic behaviour of the loads they couple to. They may be actually very small, but such purpose allows us to express the loads accurately in terms of them whilst considering equilibrium in the undeformed state - a state of pseudo-equilibrium.
