Abstract: A cantilever of uniform cross-section and density is held at an angle $ \alpha $ at one end. The shape of the cantilever depends heavily on $ \alpha $ and a nondimensional parameter $ K$ which represents the relative importance of density and length so that of flexural rigidity. Perturbations on the elastica equations for small and large $ K$ show good agreement with exact numerical integration. It is found that whenever $ K$ reaches a critical value, bifurcations of the solutions occur. This nonuniqueness can be observed by the flipping phenomena as $ \alpha $ is increased.
