If that's directed at me, I never claimed my (poor, idealised and basic) understanding of (a very small part of) the physics had any practical application. It isn't even at the stage of any possible practical application, I just figured out what the forces at play would look like if we made a...

Largely I agree. But at least one benefit I've seen from quite hard rubbers (which the physics I think backs up, but I'm open to being corrected) is you can make better closed face shots with them. A soft rubber topsheet will deform more even within the very short contact, changing the angle of...

There might be a way to measure the opposing force as a function of distance actually - it usually requires somewhat complicated equipment, but you can use a 3D printer (or anything capable of moving in small steps) and a small scale. I've used a similar technique to measure force-curves for...

Yeah obviously harmonic motion is a gross oversimplification of what is actually going on, but it's at least a refinement over a linear or parabolic model. I'm definitely not going to try to model anything beyond that, I'm not really much of a physicist, just a biologist who enjoys working with...

I know people will have mixed feelings about me reigniting this thread, but whatever, it's an interesting question and this is the only thread anywhere I've looked where people at least try to talk about this objectively. For background, I'm a sensory neuroscientist, and at least as a sensory...
