    How Can You Calculate the Elasticity of a Diving Board?

    P.S. to my last post. Although you probably surmised it, I forgot to add my point to mentioning change in reed thickness was that it would change I= bt^3/12, also supplied by Phantom Jay in the aforementioned thread.

    How Can You Calculate the Elasticity of a Diving Board?

    Ok, from the Calculator I find the formula for "cantilevered beam with uniform load", y= WL^3/ 3YI. Substituting W=ky and solving for k gives the same constant, 3YI/ L^3, supplied by Phantom Jay in the thread to which YellowPeril referred me. Having come full circle let me confirm the...

    How Can You Calculate the Elasticity of a Diving Board?

    Given my exposure to only intro physics texts your reference to a book of mechanics of materials is surely helpful. Although I've not yet checked out the Beer & Johnston perhaps you would be good enough to clarify a few points. The transverse and bending deformations sound very similar- 1) is...

    How Can You Calculate the Elasticity of a Diving Board?

    Having read said thread it sounds like a diving board, at least as it's described here with freedom to pivot, is not a good model for my reed which is not free to pivot at its clamped end on the mouthpiece in situ ( although I'd probably study it clamped onto a table ). I'm interested in...

    How Can You Calculate the Elasticity of a Diving Board?

    Trying to find please equation(s) to calculate the "elasticity", "stiffness" of a homotropic cantilever diving board. Am seeking some analogue of the spring constant of Hooke's law, F= -kx, for this 3-D system. I'm unclear about whether Young's modulus applies here given the force ( or pressure...

    Freq change- string under const tension

    Given a nylon guitar(e.g.) string stretched across 2 boundary nodes, a makeshift "nut" and "bridge" on a workbench. At the bridge end the string is tied to an overhanging weight in order to maintain const tension ( unlike a string instrument where the pegs are free to turn gradually and permit a...
