Building bridges with @physicsfun and our Catenary Arch exhibit!⠀ ⠀ Repost: Catenary Arch at Exploratorium: when an arch is built in the shape of this special mathematical curve (even with slippery blocks) the compression forces between each block are always parallel to the curve- the stack is stable with no tendency to buckle. The catenary is the exact shape of a chain hanging by its ends, also known as the hyperbolic cosine. Famously used in architecture, from the buttresses of Notre Dame to the Gateway Arch. 🌟With special thanks to the Exploratorium! ➡️ Follow the link in my profile for more info and where to find many of the amazing items featured here on @physicsfun #exploratorium #catenary #hyperboliccosine #gatewayarch #alysiod #architecture #catenaryarch #uniformload #physics #physicstoy #science #scienceisawesome

Cases Obus People began green architecture - building houses - to shelter themselves at least 30,000 years ago. Construction materials used included natural materials such as wood, animal bone, turf and boulders and person-made adobe bricks - cut and shaped stone and mortar. The assembled materials became pit houses, lake dwellings, cliff dwellings, tents and tipis and pit dwellings. Inspired by termite hills the shell houses of the Musgum also is spelled as Mousgoum people of Cameroon in West Africa are constructed using earth architecture. They are made of a mixture of dirt, straw and vegetable glue, that is dried in the sun. The vertical markings are created with forearms to reinforce the exterior of the shell, help water drain and act as a type of scaffolding so that residents can climb on the structure to make repairs. In primitive architect these dwellings and the environment were constructed in leave little margin for error in coping with natural forces: gravity, heat, cold, wind, snow, rain and flood. These constructions reveal (by their very nature) a precise and detailed knowledge of local climatic conditions and a remarkable understanding of the performance characteristics of the materials locally available. #neonurchin #neonurchinblog #dedicatedtothethingswelove #suzyurchin #ollyurchin #art #music #photography #fashion #film #words #pictures #neon #urchin #greenarchitecture #cob #adobe #cameroon #westafrica earthstructure #catenaryarch #casesobus #mousgoum #musgum (at Cameroon) https://www.instagram.com/p/CIDUMlRFMYQ/?igshid=otqntsfdc2tc

Resembling the movement of skipping stones on water, Alexandre Chan and Mário Vila Verde's Ponte Juscelino Kubitschek is composed of three asymmetrical steel catenary arches supporting the main deck of the bridge. #architecture #engineering #AlexandreChan #MárioVilaVerde #art #catenary #catenaryarch #suspensionbridge #bridge #suspended #Brasília #Brazil #JKBridge #JuscelinoKubitschek #LakeParanoá (at Juscelino Kubitschek bridge)

Cases Obus Musgum mud huts or Musgum dwelling units are traditional domestic structures built of mud by the ethnic Musgum people in the Maga sub-division, Mayo-Danay division, Far North Province in Cameroon (Musgum also is spelled as Mousgoum). The dwellings were built in a variety of shapes, such as tall domed or conical dwellings or huts, some with a reverse-V shape, and others with geometric designs. Musgum’s are an example of earth structures. Of simple design, they are constructed of mud, thatch, and water by local residents using few tools. Resembling the shape of beehives or shells, they are also known as "cases obus”. They are adobe structures, a variant of cob, and are in the catenary arch form, which can bear maximum weight with the minimum use of building materials. The dwellings also are described as "beehive type" because of their dome shape. They are considered to be an important architectural style of Cameroon, although not in fashion in the present day. #neonurchin #neonurchinblog #dedicatedtothethingswelove #suzyurchin #ollyurchin #art #music #photography #fashion #film #words #pictures #neon #urchin #greenarchitecture #cob #adobe #cameroon #westafrica earthstructure #catenaryarch #casesobus #mousgoum #musgum (at Cameroon) https://www.instagram.com/p/CIDUHLpl1O9/?igshid=1xpnl0fv2e8rt

Cases Obus The Musgum, an ethnic group in far north province in Cameroon, create their homes from compressed sun-dried mud. The tall conical dwellings in the shape of a shell (artillery) feature geometric raised patterns. What strikes at first sight is their almost organic simplicity, a second reading reveals the functions behind the forms. The walls of the houses are thicker at the base than at the summit, which increases the stability of the building. A characteristic settlement form is the “compound” - a cluster of units linked by walls. The domed huts of the Musgum people are built in shaped mud, a variant of cob. Cob building is the most widely used technique in the world, since no tools are needed - hands, earth and water are enough. The name of these houses - "cases obus” - comes from their similarity with the profile of shells. The shape of the "cases obus” is very close to the catenary arch, the ideal mathematical form to bear a maximum weight with minimal material. This profile also reduces the pressure effect of the impact of water drops on the walls. Furthermore, the extraordinary height (up to 9 meters) of these dwellings provides a cooler climate on hot days. The top of the house is pierced with a circular opening, allowing the air to circulate. It is customary to lay the mud spirally in lifts of approximately half a metre, allowing each lift to dry before adding the next. The decorative surface of each abode allows for further refinement and individualisation. The “veins” also contribute to drainage (rain). Whilst these houses require regular maintenance of their outer coating - the “veins” - as well as been decorative, allow the Musgum people to climb up the structure. Today these buildings have become somewhat obsolete with only a few groups still practicing "cases obus” construction. #neonurchin #neonurchinblog #dedicatedtothethingswelove #suzyurchin #ollyurchin #art #music #photography #fashion #film #words #pictures #neon #urchin #greenarchitecture #cob #adobe #cameroon #westafrica earthstructure #catenaryarch #casesobus #mousgoum #musgum (at Cameroon) https://www.instagram.com/p/CIDUBgflYsB/?igshid=pjg11esassle
