Vortex shedding from wind velocity in slender lightweight structures, such as flagpoles,

Vortex shedding from wind velocity in slender lightweight structures, such as flagpoles, can cause oscillations (bending vibrations) to occur mimicking loading cycles and accelerating failure due to fatigue. From a wind loading perspective, increasing the structure's natural frequency can delay the onset of vortex shedding by increasing the wind speed it begins at. Derive a material index to improve fatigue resistance by increasing the natural frequency. Natural frequency: f = @ 2
