Abstract
The oscillation of rigid rods is a simple and classical problem. The oscillation theory of rigid rods is widely applicable in various fields. However, the deformation effect on the oscillation periods of slender rods has not yet been studied. Herein we employ the energy method to derive the expression for the oscillation periods of deformable and slender rods. The derivation of the expression is straightforward. We present the deformation effect on the oscillation periods of slender iron wires. As the diameter of wires decreases and the length increases, the deformation effect becomes more significant and the percentage error of the oscillation period without including deformation effect increases. The expression for the oscillation periods of deformable and slender rods is verified by oscillation experiments.
