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.

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...

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...

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...

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...

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...
