The moment of inertia of the beam, I = Ah2/12 = 0.0052083 in4, is used for input and the critical force, Fcr =
π2EI/4 2 = 38.553 lb, is used for calculation of the applied load F. A small perturbing force is introduced in the first load step to produce lateral, rather than pure compressive,
motion. The number of equilibrium iterations for convergence increases significantly as the loading approaches
the critical load (i.e. for solutions with Θ near zero). The six displacement solutions are overlaid by displaying
with the /NOERASE option set. Results Comparison
