This teams project is to design, construct and install a Roman Arch style wooden block Puzzle(s) and peripheral information regarding their mechanics, use, and history.
ÒAn arch is a structure that spans a space while supporting weight
ÒArches appeared as early as the 2nd millennium BC
ÒAncient Romans who were the first to apply the technique to a wide range of structures,such as aqueducts, entryways, buildings, bridges and tunnels.
ÒArches continued to be used in Medieval times, especially in cathedrals, where they helped support the great weight of the stone ceilings
ÒToday, arches are common in architecture because of the stylistic and engineering benefits they offer.
The arch is significant because, in theory at least, it provides a structure which eliminates tensile stresses in spanning an open space. All the forces are resolved into compressive stresses. This is useful because several of the available building materials such as stone, cast iron and concrete can strongly resist compression but are very weak when tension, shear or torsional stress is applied to them.
