Problem 5. Let X be a topological space. Assume that, for every pair of disjoint closed subsets E and F of X, there exists a continuous function f: X \to [0, 1] such that $E \subseteq f^{-1}(\{0\})$ and $F \subseteq f^{-1}(\{1\})$. Prove that X is normal. (This is the converse of the Urysohn lemma.)

When the displacements and displacement gradients are small, the second Piola-Kirchhoff stress is approximately equal to the Cauchy stress. Thus, for small vibrations of an elastic system, the motion equation reduces to: Î”Xi Assuming Hooke's law T = Xe + 2Gei, where e = Îµ and X and G are the Lame elastic moduli, show that the equation of motion then leads to the following displacement equation of motion: a^2u
