Approximate solutions for the critical load of an axially loaded strut, and for the deflection produced in an eccentrically loaded strut, are obtained by the Energy Method. For most practical purposes these solutions compare favourably with solutions based on successive approximation, since for the same accuracy the time required for a solution by successive approximation is much greater.
