Problem1.3 Consider straight prismatic bar shown below. The longitudinal displacement is given by u(x,t). Dynamically varying stress field is $\sigma(x,t)$ and the body force $q(x,t)$ per unit volume. For this bar, derive the one-dimensional wave motion (i.e., 1D wave equation) in the absence of body forces.
