the impulse (force/time) is probably a better measure
- yarg 3y agoImpulse isn't force over (divided by) time, it's the integral of force over (with respect to) time.
- just_boost_it 3y agoIts really a sound wave pulsing through the grey mush of each brain, so some measure of stress (force/area) or strain (differential displacement/area) might be the beast way to look at it. The damage might be done in shear where the center of the brain moves while the outside is stuck to the skull, but it would be really hard to measure that. Maybe woodpecker brains are more free to wobble around inside their skulls so shear stresses and strains are lower than they are in people?
- jessriedel 3y agoBased on eyeballing the charts here, it looks like (accel)^4(time) better approximates the boundary of human endurance: doubling the number of gees cuts the amount of endurable time by more like a factor of 16 than 2. https://space.stackexchange.com/questions/6154/maximum-survivable-long-term-g-forces https://space.stackexchange.com/questions/6154/maximum-survi...
