Abstract	Short non-flexible elements of cable were driven harmonically in water while constrained by springs. The cable elements were observed to oscillate at approximately the Strouhal vortex shedding frequency. Damped resonance occurred near the point where the natural frequency and the Strouhal vertex shedding frequency were equal. Transverse oscillation amplitudes greater than one and one half cable diameters and hydrodynamic drag forces as much as seven times that normally experienced by rigidly constrained cylinders were observed in the neighborhood of the resonance point. A simple second order mathematical model was constructed which closely approximates the cable elements transverse response in the neighborhood of the resonance point.
