unreferenced date August 2009 Image SlipperyHitchOnRoyalYard.jpg thumb right 200px A gasket holding the main royal on a modern square rigged training ship. In sailing , gaskets are lengths of rope or fabric used to hold a stowed sail in place. In modern use, the term is usually restricted to Square rig square rigged ships, the equivalent items on yachts being referred to by the more prosaic sail ties . On most ships, gaskets are made of rope . They are attached to the top of the yardarm yard and, left loose, would hang behind the sail. Gaskets should never be left dangling, however, so when the sail is set they are brought around underneath the yard and up the back of it and then tied to the jackstay metal rod where they originated. Alternatively, longer gaskets particularly the clew gaskets described below can be secured using a gasket coil . When the sail is to be stowed it is first folded and bagged neatly within itself, pulled onto the top of the yard, and then the gaskets are brought round over it and secured to the jackstay to hold it in place. Gaskets should be tied with a slippery hitch to enable them to be let off quickly, though if the yard is large there may only be enough rope to form a clove hitch when the gasket is brought round it. Most ships are equipped with clew gaskets at the outer ends of the yards. These do not pass around the sail, but through a shackle or ring on the blocks of the sheet sailing Square rig sheet . Pulled tight and secured to the jackstay or the yard s lift, this takes the load off the Clewlines and buntlines clewline and sail, and should allow the blocks to be lifted higher, dragging the sail down less and enabling a neater stow.

Image Apollonian circles.svg thumb right 350px Some Apollonian circles. Every blue circle intersects every red circle at a right angle. Every red circle passes through the two points, C and D , and every blue circle separates the two points. This article discusses a family of circles sharing a radical axis , and the corresponding family of orthogonal circles. For other circles associated with Apollonius of Perga , please see the disambiguation page, circles of Apollonius . Apollonian circles are two families of circle s such that every circle in the first family intersects every circle in the second family orthogonal ly, and vice versa.

In geometry , tangent circles also known as kissing circles are circles in a common plane that intersect in a single point. There are two types of tangent tangency internal and external. Many problems and constructions in geometry are related to tangent circles such problems often have real life applications such as trilateration and maximizing the use of materials. Two given circles Steiner chains main Steiner chain Pappus chains main Pappus chain Three given circles Apollonius problem main Problem of Apollonius Apollonius problem is to construct circles that are tangent to three given circles. Apollonian gasket main Apollonian gasket If a circle is iteratively inscribed into the interstital curved triangles between three mutually tangent circles, an Apollonian gasket results, one of the earliest fractals described in print. Malfatti s problem main Malfatti circles Malfatti s problem is to carve three cylinders from a triangular block of marble, using as much of the marble as possible. In 1803, Gian Francesco Malfatti conjectured that the solution would be obtained by inscribing three mutually tangent circles into the triangle a problem that had previously been considered by Japanese mathematician Ajima Naonobu these circles are now known as the Malfatti circles , although the conjecture has been proven to be false.

In geometry , Coxeter s loxodromic sequence of tangent circles is an infinite sequence of circles arranged such that any four consecutive circles in the sequence are pairwise mutually tangent. This means that each circle in the sequence is tangent to the three circles that precede it and also to the three circles that follow it. The radii of the circles in the sequence form a geometric progression with ratio math k varphi sqrt varphi approx 2.89005 , math where is the golden ratio . k and its reciprocal satisfy the equation math 1 x x 2 x 3 2 2 1 x 2 x 4 x 6 , math and so any four consecutive circles in the sequence meet the conditions of Descartes theorem . The centres of the circles in the sequence lie on a logarithmic spiral . Viewed from the centre of the spiral, the angle between the centres of successive circles is math cos 1 left frac 1 varphi right approx 128.173 circ . math The construction is named after geometer H.S.M.
