Talk:Basket-handle arch

Basket-handle arch

Pointed arches are not Basket handle arches
The lede for the article states ...

"A basket-handle arch is an arch with the profile of its intrados (inner surface) formed by a sequence of circular arcs with neighboring ones being tangent to each other (smoothly transitioning), and the end ones tangent with supports."

The pointed arch has a pointed crown, not a smooth transition. All the example bridges have smooth crowns. It is one of the characteristics of these types of arches, they have an odd numer of centers. Practically speaking, how could one pick up or carry a "crowned handle"? I propose reverting the change to the previous edit which was ogive. Does anyone have better thoughts? Cheers Risk Engineer (talk) 16:37, 29 June 2024 (UTC)


 * I disagree. Few points to consider:
 * The ogive is not a smooth curve (see the illustration there). In a 2D version, it is the same as a two-centered pointed arch.
 * The same article also establishes equivalence between "ogive arch", "pointed arch", "Gothic arch" in the section Ogive.
 * "Ogive arch" is way less popular than "pointed arch" in English
 * The intent of the paragraph in question is not to say that pointed arch and basket arch are relatives (neither is the segmental arch discussed in the adjacent sentence). The text IMHO speaks about inflexibility of the semicircular arch (where the rise has to be equal to half of the span) and ways around it: shorten the arc segment, creating a segmental arch, use two arc segments (pointed arch), use three segments (basket arch), use ellipse.
 * That said, the text is somewhat confusing, in particular, it does not state #4 here clearly enough. It can benefit from some WP:CE. Викидим (talk) 17:00, 29 June 2024 (UTC)
