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!!!

Pressure in materials is highest in corners.
Stuff in the barrel won’t break the planks of the barrel by breaking the planks. It pushes on all planks inside the barrel trying to push them away from eachother.
The circle shaped top and bottom only prevent planks from going inside, it basically makes the shape and makes it watertight.
So if stuff inside the barrel wants to push the planks to the outside it pushes everywhere, but if planks get lose from the top and bottom the barrel is broken. So here you put a ring around the planks so the planks can’t move to the outside.
Also they make the planks curved. It makes the corners more round.But another thing barrels have to do beside keeping stuff inside is they have to be stackable.
If barrel is on the side and other barrels get put ontop of it, the weight wants to make the curved planks straight, so they want push themselfs away from the top/bottom but the rings keeps them together.
If barrel is normal placed and gets other barrels ontop of it, the weight wants to make the planks more curved. Planks can’t move to the inside because of the top and bottom.
But because planks get more curved, tension gets increased like a bow. So planks want to push to the outside more and get lose from the top or bottom. This is prevented by the rings.
