Temperature, Frequency, and Young’s Modulus of an Aluminum Tuning Fork
by Zachery L. Greer
Abstract
The frequency produced by a standard C (523.3 Hz) aluminum alloy tuning fork when struck at temperatures ranging from 29˚C to 300˚C was studied. It was found that frequency decreased with increasing temperature with an inverse exponential relationship. The frequency was used to calculate Young’s Modulus for aluminum, with the results being in close agreement with published values.
