wine barrel parts






barrels have convex shape , bulge @ center, called bilge. facilitates rolling well-built wooden barrel on side , change directions little friction, compared cylinder. helps distribute stress evenly in material making container more curved. barrels have reinforced edges enable safe displacement rolling them @ angle (in addition rolling on sides described).
