In some areas of geometry and topology the term cylinder refers to what has been called a cylindrical surface. A cylinder is defined as a surface consisting of all the points on all the lines which are parallel to a given line and which pass through a fixed plane curve in a plane not parallel to the given line.

The ibex, a native of the Zagros Mountain range near Susa, is portrayed in a non-naturalistic style using simple shapes such as triangles. [1] [3] The goat's horns are depicted as arched back over its body, forming a circle. [5] The roundness of the horns and other geometric elements of the bushel are said to emphasize its cylindrical shape. [1]
A cylindrical coordinate system is a three-dimensional coordinate system that specifies point positions by the distance from a chosen reference axis (axis L in the image opposite), the direction from the axis relative to a chosen reference direction (axis A), and the distance from a chosen reference plane perpendicular to the axis (plane ...
A Nissen hut is a prefabricated steel structure originally for military use, especially as barracks, made from a 210° portion of a cylindrical skin of corrugated iron. It was designed during the First World War by the Canadian-American-British engineer and inventor Major Peter Norman Nissen .
Horizontal cylindrical tanks are typically used for transport because their low-profile creates a low center of gravity helping to maintain equilibrium for the transport vehicle, trailer or truck. A Hydro-pneumatic tank is typically a horizontal pressurized storage tank.
The various cylindrical projections are distinguished from each other solely by their north-south stretching (where latitude is given by φ): The only normal cylindrical projections that preserve area have a north-south compression precisely the reciprocal of east-west stretching (cos φ). This divides north-south distances by a factor equal to ...
In this manufacturing process glass is blown into a cylindrical shape by a glass blower. The ends of the cylinder are cut off and a cut is made down the side of the cylinder. The cut cylinder is then placed in an oven where the cylinder unrolls into a flat glass sheet.
It is usually formed into triangular or cylindrical shapes, and wrapped in nori (seaweed). [a] Onigiri traditionally have sour or salty fillings such as umeboshi (pickled Chinese plum), salted salmon, katsuobushi (smoked and fermented bonito), kombu, tarako or mentaiko (pollock roe), or takanazuke (pickled Japanese giant red mustard greens).
