Question 4 [15 Marks] A metal column has a power law stress-strain relationship shown in Eqn.1, where the k and n are materials constant. Assume that the critical buckling length is Ler, the moment of inertia is I and the cross section area is A. Using the tangential modulus method to derive the critical buckling force (Ner) for the column: express your solution as function of k, n, I, A and Ler. o = kɛ" (Eqn. 1)
