# Boundary conditons and initial conditions of a vibrating rod

 P: 13 Finding the vibrational motion of a rod. A uniform rod of lenght l is compressed from both ends so that its new lenght becomes l(1-2 $$\epsilon$$). The compression force is then removed and the rod is left to vibrate freely. Find the subsequent vibrational motion of the rod. What are the initial conditions and boundary conditions for this question?
