- Title
Euler-Bernoulli beam theory in the kitchen: The fridge-violin.
- Authors
Darmendrail, Luis; Müller, Andreas
- Abstract
An application of the Euler-Bernoulli beam theory (a classic in vibration and acoustics) to a curious sound phenomenon occurring in a daily life situation is presented. A smartphone is used as an experimental tool to measure and analyse the acoustic signal. The experimental data are compared to a prediction from the Euler-Bernoulli model, yielding satisfactory agreement. Limitations of the analysis are discussed. The low-cost nature and the investigation of a curious phenomenon make the example a good candidate e.g., for undergraduate lab-work courses or research projects, which can spark students interest in acoustics, and more generally develop their interest and skill in applying physics to phenomena of everyday life.
