Once again, thanks so much for taking the time to look these things up and answer my questions. You do the quest a service
I tried looking up how Hooke's law applies to substances like wood, saw the huge matrix on wikipedia, and gave up.
1123m/s is a velocity I'm much more happy with, given the fastest guns fire bullets in the 790m/s range. Great point about the Banshee slayer seal! I don't know how I could forget, but setting it to mute all volume(or whatever it's maximum is) effectively removes wind speed from the bullet accuracy equation, right? Are you saying that the seal would also reduce air drag on a projectile? That makes sense to me, since high enough drag would produce a sound, so I suppose the question becomes, is the drag the source of the sound or is it air that's already reduced the speed of the bullet? Wait, since the bullet will be supersonic, is there a chance that the seal won't activate since 'sound' will never catch up to it? Guess it depends on what the seal classifies as sound. I could be thinking about this the wrong way, since the sound originates at the bullet and the seal is the 'listener.' Sorry for bugging you, but these things aren't clear to me.
edit: after reading
this, I think there's a decent chance banshee slayer seals could classify sound in a way that excludes shock waves. If shock waves aren't created instantaneously, instead formed by quickly compressing sound waves, then a sonic boom would never occur. Man, things get weird when you start ignoring physics.
Ah, classic. I mixed up the diameter and the radius, leading to an impossibly high tip speed for the centrifuge in the link. I'll give ultracentrifuges a look, thanks
They sound scary. If you like,
here's a video I found of spinning CDs up to their breaking threshold. Also,
light-gas guns.
