caption_attribution_description: English: Made by myself. I melted a borosilicate capillary tube with a blowtorch into the shape (a en:cantilever beam) seen, clamped it in a micrometer (that's what micrometers are for, yes?), and photographed it vibrating. Flash photo + 1/8 second exposure to show vibration and a frozen moment in one picture. A micrometer was used because it has carbide faces which are four times stiffer than glass (and twice stiffer than steel), makes for an excellent cantilever beam mount. Though I've had problems with poorly clamped beams, this probably makes no difference but it makes me sound smarter. This photo was selected out of 59 tries.
context_page_description: Euler–Bernoulli beam theory is a simple method to calculate bending of beams when a load is applied. This applies to small deflections of a beam without considering effects of shear deformations. Therefore, it can be considered a special case of the Timoshenko beam theory. It was first introduced around 1750. It gained popularity during the development of the Eiffel Tower and the Ferris wheel in the late 19th century. After that, it was used in many engineering fields including mechanical engineering and civil engineering. Although other advanced methods have been developed, the Euler-Bernoulli beam theory is still widely used because of its simplicity.
