It is very counterintuitive when you reason in terms of weight though. If you imagine a pile of rocks for instance, it makes sense that the strain on the base of a pyramid is lower than on the base of a column of the same height and base area.
You have to visualize the atmospheric air pressure to reconcile the result with intuition.
- ummonk 5y agoI mean it's perfectly intuitive to me that a pyramid of rocks isn't going to collapse, so you don't need a container to hold it in. The closer analogue would be pouring sand in to a tube vs. pouring it in to a bottle that widens below the neck - it's intuitive to me that the bottle would be under enormous strain to hold the sand in. (And, incidentally, the part of the bottle where it widens would be applying extra "weight" to the sand below it)
