Description

Vibrating string

Additions

This model depicts the solution of the one-dimensional oscillation equation: \[ \frac{\partial^2 y}{\partial t^2}= c^2 \cdot \frac{\partial^2 y}{\partial x^2}\ .\]

This equation describes for example the oscillation of a piano string or a guitar string. For this model, a curve shaped displacement in one of the intervals was selected as initial condition.

This kind of displacement happens frequently while picking strings. Additionally it is assumed that the string is fixed at the endpoints. This displacement happens for example at guitar strings.

According to his account Saint Venant provides this modell with the Sociètè Philomathique de Paris
