  • Consider a dam that is 10m tall

    Then consider the height of water behind that dam is 5m tall.

    Does the dam need to be built stronger if the water behind it is 1 km long?

    How about only 500m?

    How about 1m?

    The answer is, it doesn’t matter. Water exerts pressure equally regardless of how much water is behind it.

    Therefore a graduated cylinder that is 10m tall needs to resist the same amount of force as a dam 10m tall regardless of how much water is behind the dam. Even a thin sliver of water 1mm thick and 5m tall has the same force as a 5m lake behind the dam.

    Incompressible fluids are pretty insane












  • I’m in the US military. The fact that qualifying on an M4 is 23 out of 40 tells you a lot. (Although my unit’s average is closer to 30ish)

    Additionally, a very little amount of the military is combat arms roughly 15%. The other 85% supports the warfighter. I’m part of the 85%

    This is why the US military is so logistically and maintenance heavy because we all support the 15%.

    However shrapnel will cause a lot of damage and hopefully take out the brain with enough luck. The brain could still be alive without a body to support it.

    Also depends on what kind of zombies we’re talking about. If it’s a zombie that still relies on oxygenated blood, then conventional tactics will still apply. However if the zombie only needs non-degraded muscles to keep moving, then it’ll take a while for tactics to change.
