Standing waves on a string experiment -- Relative amplitude of harmonics

[coquelicot]

Yet, your explanation has "some chance" only if the string has reached the limit of its linear elasticity, which is unlikely to be the case in general. I agree that the OP has provided insufficiently many details though (post #7 again).

Yet, your explanation...

For the n-th time: This wasn't my entire explanation, just one of the factors I mentioned that can play a role, since we are talking generally without specific data.

OK. Thank you for this discussion, and especially for #22 where I've learned something.
