Vibrating glass beam

The vibration of a beam, such as this cantilever made of borosilicate glass, can be described with the Euler-Bernoulli beam equation alongside a loading function which includes inertia, gravity, and possibly drag, and functions describing the variable section modulus and linear density. The traces of the exposure show decaying oscillations and motion that is not simple harmonic.
