Abstract : The dynamic stability of a cable stretched between two supports is analyzed. The cable is exposed to a uniform, incompressible flow at an angle to the cable axis. Fluid forces are taken to be the quasi-static components of pressure drag and friction drag. Response due to vortex shedding is not considered. A new instability is found which is wavelike in character and has dominant amplitude at the rear support. The instability is accounted for.
