A Comparison of Shaft Frequencies

Shaft vibrational frequency is a quantitative measurement of the rate of vibration (oscillation) of a shaft as expressed over a known unit of time. In the late 1970's a few individuals began working on developing a way to identify a quantitative measurement of shaft stiffness to be able to ensure a more accurate progression of stiffness through sets of golf clubs. Vibrational frequency became a viable method for more accurately identifying such a relationship because it was a quantitative measurement which took some of the shaft's bending properties into account.
