Consider now a clamped-free column subjected to a load P constrained to remain tangential to the free end of the column as it deforms (Fig. 9.23). You may verify that this is a nonconservative problem, as the loading is pathdependent. What are the boundary conditions at x = L? Show that the solution for the Euler equation subject to the boundary conditions for this problem leads to the characteristic equation.
What does this imply about the buckling load? Why do we obtain this result?
