Vibrating glass beam[edit]

Original
Reason
A flash photo freezes in time the extent of vibrations of a cantilever beam, exposure beyond flash reveals the whole path of the beam and creates an interesting effect with the lighting (which consists exclusively of a carefully positioned 1 watt LED flashlight). The vibrations rendered in white against the black background lend to a very diagrammatic appearance which works well for the article it's in. Post processing involved only resize and slight sharpening. The beam was melted from a capillary tube and that took about 20 tries to get right. I need to go buy some more tubes.
Proposed caption
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.

  • Support. There's motion blur, but since it's a photo of a vibrating object, I think that's unavoidable. -Hit bull, win steak(Moo!) 15:18, 17 September 2007 (UTC)[reply]
  • Weak Support The motion blue helps visualize the vibration. It's pretty much essential, even if it were avoidable. Puddyglum 17:38, 17 September 2007 (UTC)[reply]
