Tuning Forks in Neurology Tuning forks are used in the diagnosis of nervous afflictions known as large-fiber polyneuropathies, which are often manifested in the form of reduced sensitivity to vibrations. Disorders that can result in this type of pathology include diabetes and nerve damage from exposure to heavy metals. The tuning fork here has a frequency of 170 Hz. vmax=1.55 m/sFind their maximum acceleration. Give your answer as a multiple of g.
