👉 In mechanics, a monohull is a shape or structure that can be completely enclosed by two identical rectangular sections. These segments are called flanges and they provide a stable and rigid foundation for structures. Monohulls are characterized by having no internal space between their sides, which allows them to be used as supports in several engineering applications such as ships, tanks, and aircraft wings. They serve as the base of many designs due to their stability and resistance to deformation.
