So I’m not English speaker so forgive me if I use the wrong terms. Why do barrels or casks (dunno the right term) have more concentrated hoops towards the end and not at the center?
I think it is about pressure but I do not fully understand why? Is this because when they are not placed on the side the highest pressure is below?
You can also explain like I’m 10 if you fin dir easier.
Thnak you!!!

So the sides of those kinds of barrels are made from staves, those long vertical pieces of wood, and the staves are originally straight pieces of wood that are bent into a curve when being made into a barrel. They are under tension in the barrel; on the ends, the hoops hold the staves inward. The center parts of the staves don’t collapse inwards because they all hold each other, kind of like all the pieces of a stone arch.
So because of this, on the top and bottom (ends), there is a lot of outward force that the hoops need to hold, but in the middle the hoops only need to keep the staves from hopping beside each other and collapsing the “arch”, so they aren’t holding as much outward force.
Here is a short video showing the basics of barrel construction; it doesn’t directly answer your question, but with my comment it should help. https://youtu.be/X56uglze1G0?si=uI8QbAErCLSNkKvL
