Abstract

In this thesis we introduce the problem of the ideal homogeneous hanging cable called the catenary. We observe the behaviour of the shape of the curve. Firstly, we solve the problem of the classical catenary on a flfat Earth, where the gravitational fifield is constant and perpendicular to the ground. Secondly, we focus on the true symmetric catenary in the central gravitational fifield, which comes from the -1/r potential. In both cases we use the method of calculus of variations for isoperimetric problems and in particular the Euler-Lagrange differential equation. Lastly, we explain the problem of the asymmetric case.

Secondary title: Prava verižnica
Secondary abstract: V tem diplomskem delu predstavimo problem idealne viseče homogene vrvi, ki jo imenujemo verižnica, in opazujemo obnašanje oblike te krivulje. Najprej rešimo problem klasične verižnice na ravni zemlji, kjer je gravitacijsko polje konstantno in pravokotno na podlago, nato pa se osredotočimo na pravo verižnico v središčnem gravitacijskem polju, ki je dobljeno iz -1/r potenciala. V obeh primerih uporabimo metodo variacijskega računa za izoperimetrični problem, še posebej Euler-Lagrangeevo diferencialno enačbo. Nazadnje razložimo tudi problem asimetrične verižnice.
