Unformatted text preview: Problem 3 The equation of motion of the longitudinally vibrating rod (i.e., vibrating in the axial direction) is give as: where, p and E are density and Young's modulus of the material of the rod and ii is the &lacement at a point of the rod. The stress and displacement relation ship is: au E  a ax Find the wave speed in the rod. A rod with fixedfree boundary conditions is shown below. Suppose we have a displacement wave traveling as shown. Sketch the shape of the wave that will be  reflected from the free end....
