A slender bar of cross-sectional height h, and area A, fixed at the base and free at the upper end, is loaded with
a value larger than the critical buckling load. Determine the displacement (∆X, ∆Y, Θ) of the free end and display
the deformed shape of the bar at various loadings. Figure 136.1 Buckled...
