There are three different configurations of arches including the fixed arch, the two-hinged arch, and the three-hinged arch. These configurations determine how stable the arch will be. Types of arches include the triangular arch, semi-circular arch, segmental arch, rampart round arch, lancet arch, equilateral pointed arch, and jack arch. Additional types of arches include the trefoil arch, horseshoe arch, three-centered arch, elliptical arch, inflexed arch, ogee arch, reverse ogee arch, Tudor arch, and parabolic arch.
an arch bridge weakness is not having enough streanth to hold up the middle
It is all about the arch. Throughout the history of building people figured out that an arch is the strongest form of support for a doorway or tunnel. The reason is that any weight on the arch is all directed to the middle so that the entire arch is helping to support the weight. If you have a straight line roof, weight at the center is supported only at the area that is in contact with the weight.
I think it's the New River Gorge Bridge in West Virginia.
compression: the keystone in particular is under rather high compression forces.

Arch
An extended arch is called a vault. Most tunnel are built using vaults. It's a bunch of arches put together.
That forms an overhead arch; all-embracing or overwhelming
The New Balance - 858 gives excellent arch support, it has an extended web along the TK for more support.
I guess you mean Arch as in Archway? It's known for its strength - compared to a straight surface formation.
First branchial arch also known as the mandibular arch is the right answer.
The croquet arch is known as a hoop. The objects used to hit the balls in croquet are called mallets.

A arch
Yes, it does. Part of its strength comes from the use of flying buttresses as added support. Typically, pointed arches are used to support thinner walls for aesthetic purposes, but can handle increased overhead weight.AnswerI'm almost positive that it does. I think it is the keystone (very center stone in a rounded arch) that is the downfall of a rounded arch. This only holds so much weight. I believe that the pointed arch holds most of its weight on the "legs"
