Horseshoe shape is a shape in which the length of the opening is approximately between a third or a quarter of a circle's circumference. [1] It therefore resembles a horseshoe. The shape is sometimes described as keyhole, omega-shaped or moon-like. [2] It occurs most frequently in the horseshoe that gives it its name.
The mouth of the horseshoe had a post set just inside it, and in the centre of the horseshoe there was a boulder with some burnt bone near it. [2] In the second phase the timber posts were replaced by a horseshoe setting of 8 standing stones, about 8 metres by 6 metres. [2] This was surrounded by a stone bank around 17 metres in diameter.

The horseshoe map was designed to reproduce the chaotic dynamics of a flow in the neighborhood of a given periodic orbit. The neighborhood is chosen to be a small disk perpendicular to the orbit . As the system evolves, points in this disk remain close to the given periodic orbit, tracing out orbits that eventually intersect the disk once again.
Horseshoe arch. The horseshoe arch (Arabic: قوس حدوة الحصان; Spanish: arco de herradura), also called the Moorish arch and the keyhole arch, is a type of arch in which the circular curve is continued below the horizontal line of its diameter, so that the opening at the bottom of the arch is narrower than the arch's full span.
In celestial mechanics, a horseshoe orbit is a type of co-orbital motion of a small orbiting body relative to a larger orbiting body. The osculating (instantaneous) orbital period of the smaller body remains very near that of the larger body, and if its orbit is a little more eccentric than that of the larger body, during every period it ...
Many patterns made with cables do not have a rope-like quality. For example, a deep honeycomb pattern can be made by adjacent serpentines, first touching the neighbor on the left then the neighbor on the right. Other common patterns include a "Y"-like shape (and its inverse) and a horseshoe crab pattern.
The horseshoe is heated and a hole is punched through 90 percent of the steel with a forepunch or drift punch. The pointed end of the tool should be kept sharp so that the burr is cut out smoothly. The punched hole is lined up over the pritchel hole and the pritchel is driven into the hole, knocking out the remaining metal at the bottom of the ...
Nevertheless, the simpler horseshoe vortex model used with a reduced effective wingspan but same mid-plane circulation provides an adequate model for the flows induced far from the aircraft. The term horseshoe vortex is also used in wind engineering to describe the flow pattern created by strong winds around the base of a tall building. This ...
