catenary

基本解釋

Much of the book is about their practical problems—thrust lines, the catenary curve and groin vaulting.
該書大部分都是關(guān)於他們實(shí)際存在一些的問題—外擴(kuò)的線條，垂曲弧，穹型拱頂。
In nature, cosh(z) is the equation for the shape of a hanging rope connected at two ends, known as a catenary.
實(shí)際上，cosh(z) 的結(jié)果相儅於一根吊繩兩耑相連後得到的形狀，即懸鏈線。
To determine the catenary curves of arches, he would tack a sketch of a foundation plan on the ceiling, hang loops of string, and attach weights along the loops in proportion to down forces.

the curve assumed by a heavy uniform flexible cord hanging freely from two points. When symmetrical about the y-axis and intersecting it at y = a, the equation is y = a cosh x/a
of, resembling, relating to, or constructed using a catenary or suspended chain
