Wheel

A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the main components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel and flywheel.

Common examples are found in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity, or by the application of another external force or torque.

Etymology

The English word wheel comes from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *k^wek^wlo-, an extended form of the root *k^wel- "to revolve, move around". Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, the latter both meaning "circle" or "wheel".

Parallel curve

A parallel of a curve is the envelope of a family of congruent circles centered on the curve. It generalises the concept of parallel lines. It can also be defined as a curve whose points are at a fixed normal distance from a given curve. These two definitions are not entirely equivalent as the latter assumes smoothness, whereas the former does not.

A parallel curve is also called an offset curve and this is the preferred term in CAGD. (In other geometric contexts, the term offset can also refer also to translation.) Offset curves are important for example in numerically controlled machining, where they describe for example the shape of the cut made by a round cutting piece of a two-axis machine. The shape of the cut is offset from the trajectory of the cutter by a constant distance in the direction normal to the cutter trajectory at every point.

In the area of 2D computer graphics known as vector graphics, the (approximate) computation of parallel curves is involved in one of the fundamental drawing operations, called stroking, which is typically applied to polylines or polybeziers (themselves called paths) in that field.

Sensation

Sensation refers to the processing of senses by the sensory system; see also sensation (psychology).

Sensations (film)

Sensations is a 1975 pornographic film written by Veronique Monet and directed by Lasse Braun. It stars the writer and Brigitte Maier, and it features an appearance by Tuppy Owens. It was exhibited at the Cannes Film Festival and became the first European pornographic film to be distributed in the USA.

Afternoons in Utopia

Afternoons in Utopia is the second album released by Alphaville in 1986, by Warner Music. The album was recorded between September 1985 and May 1986, and Alphaville employed no less than 27 guest musicians and singers to record the songs. 500,000 copies of the album have been sold.

Reviews

Reviews for this album were again generally positive, with one reviewer saying "at points things are just bad yup-funk for wine bars, but a couple of misfires aside, Afternoons in Utopia holds up well" and "in retrospect it's actually a successful endeavour, perfectly evocative of a mainstream style." The album finished in the Top 20 in five European countries and at #174 the US. Another reviewer points out that "by the time of this album's 1986 release, synth-pop was no longer a chart concern."

Album notes

The album's lyrics make several references to cosmic entities ("sci fi" as one reviewer called it), including comets, the planet Mars and its landscape, and a starship. When the word "smile" is used in the songs "Afternoons in Utopia," "Lassie Come Home," and "Red Rose," it's printed in the liner notes as the acronym S.M.I².L.E., a reference to Timothy Leary, which stands for "Space Migration, Increased Intelligence, [and] Life Extension."
