A round tournament style crokinole board. Boards may also be octagonal, which is the more traditional shape. Board dimensions vary with a playing surface typically of polished wood or laminate approximately 26 inches (660 mm) in diameter. The arrangement is 3 concentric rings worth 5, 10, and 15 points as you move in from the outside.
By the 1870s all houses were constructed with cast iron gutters and down pipes. The Victorian gutter was an ogee, 115 mm in width, that was fitted directly to the fascia boards eliminating the need for brackets. Square and half-round profiles were also available.
The mortar squad leader verifies the number of charges; then the assistant gunner drops the round down the muzzle of the tube. The round, pulled by gravity, accelerates down the smooth bore of the mortar until the primer (in the base of the tail boom of the round) strikes the firing pin located in the bottom of the mortar tail assembly. The ...
The hydraulic diameter, D H, is a commonly used term when handling flow in non-circular tubes and channels. Using this term, one can calculate many things in the same way as for a round tube. When the cross-section is uniform along the tube or channel length, it is defined as [1] [2] =, where
A four-hole extension to ISO 838 is also in common use. Two holes are punched in accordance with the standard, plus two additional holes located 80 mm to the outside of the standard holes. The two additional holes provide more stability in 4-ring binders, while still allowing 4-hole paper to fit 2-ring binders.
The name "Borromean rings" comes from the use of these rings, in the form of three linked circles, in the coat of arms of the aristocratic Borromeo family in Northern Italy. [ 9 ] [ 10 ] The link itself is much older and has appeared in the form of the valknut , three linked equilateral triangles with parallel sides, on Norse image stones ...
The rings are often 6 to 25 feet (1.8 to 7.6 m) in diameter and often occur in groupings. The rings of stone held down the edges of animal skin hides of the cone-shaped tipis, to keep them snug against the ground. The general pattern of a tipi (also "tepee") ring is an east-facing entrance, where there are no stones, and a heavily anchored side ...
The orientation of the rings is consistent with an edge-on view from Earth in 2008, explaining the observed dimming of Chariklo between 1997 and 2008 by a factor of 1.75, as well as the gradual disappearance of water ice and other materials from its spectrum as the observed surface area of the rings decreased.
