what shapes are in bridges
Triangles and octet-trusses are used alot in bridges become they hold their shape well when subject to a variety of stresses. However hexagons and lorimerlite frameworks are u â¦ sed in different conditions, where they must resist only compression as opposed to a variety of stresses.
In the same way that triangles make strong flat shapes, they also make strong shapes in three-dimensions. The atoms inside a diamond are arranged as many connected tetrahedrons, and that is why a diamond is such a hard and strong material.
