  • Rod String - an overview

    Figure 4.2 shows a rod string section with a uniform cross-sectional area, A, and length, L.The coordinate axes x and u are directed downward and represent axial distance and displacement of the rod along the string, respectively. In order to find the governing equation for the movement of the string, a force balance must be written for an incremental element of the rod.
