In the offshore oil and gas industry, "catenary" refers to a steel catenary riser, a pipeline suspended between a production platform and the seabed that adopts an approximate catenary shape. The mathematical properties of the catenary curve were studied by Robert Hooke in the 1670s, and its equation was derived by Leibniz, Huygens and Johann Bernoulli in 1691.Ĭatenaries and related curves are used in architecture and engineering (e.g., in the design of bridges and arches so that forces do not result in bending moments). Galileo Galilei in 1638 discussed the catenary in the book Two New Sciences recognizing that it was different from a parabola. A hanging chain will assume a shape of least potential energy which is a catenary. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. Mathematically, the catenary curve is the graph of the hyperbolic cosine function. Rope statics describes catenaries in a classic statics problem involving a hanging rope. The catenary is also called the alysoid, chainette, or, particularly in the materials sciences, funicular. The curve appears in the design of certain types of arches and as a cross section of the catenoid-the shape assumed by a soap film bounded by two parallel circular rings. The catenary curve has a U-like shape, superficially similar in appearance to a parabola, which it is not. In physics and geometry, a catenary ( US: / ˈ k æ t ən ɛr i/, UK: / k ə ˈ t iː n ər i/) is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends in a uniform gravitational field. Here is a comparison of both products.The silk on a spider's web forming multiple elastic catenaries. The later is a strictly realistic vehicle simulation. The first is focused on gameplay and easy setup. I’m now working on them and new updates will be available regularly.ĭocumentation is available for getting started with the project:Įdy’s Vehicle Physics complements my other vehicle simulation project, Vehicle Physics Pro. Some features and vehicles available in the old version are yet to be moved here. Fixes the problems with the WheelCollider in Unity 5.Vehicles are simple to configure providing predictable results.The key features as result of the new design are: As result, I decided to start from scratch and write a completely new vehicle physics simulation. The major changes in the physics in Unity 5 made impossible to update the vehicle physics while keeping the compatibility with previous Unity 4 projects. That is… free for Level 11 subscribers!Įdy’s Vehicle Physics 5 is not a simple upgrade. The popular vehicle physics package Edy’s Vehicle Physics is available for Unity 5 since April 1st as part of the Unity’s Level Eleven promotion.
