Sphere (Polish band)

Sphere is a Polish brutal death metal act, rooted in an old school death metal. Established in Warsaw, Poland in 2002, with Bolek (guit), Val (guit), Th0rn (dr) and Jasiek (voc) as the original members. In 2004, after several line-up changes, the band released a Spiritual Dope demo.

In 2005, Analripper, known also from death/grind Pyorrhoea, joined the band as the vocalist.

On 20 January 2007, the band debuted with the Damned Souls Rituals LP, released through Empire Records. The album was recorded in Zed Studio, Olkusz, Poland and was spread out in 5000 copies.

Three years later, in 2010 Sphere entered Zed Studio again to record their second album. The Homo Hereticus was released by Masterful Records on 10 February 2012. The music stemmed from death metal origin yet was enriched with fresh groovy ideas. For the next two years the band played a number of concerts including the ones with bands such as Cannibal Corpse, Cryptopsy, Vital Remains, Obituary, and Disgorge. In the meantime another personal changes took place and in July 2014, including: Th0rn – drums, Diego – guitars, Beton – bass, Iron – guitars, Dawidek – vocals, Sphere recorded the material for their third Mindless Mass LP. The whole recording process was supervised by Filip 'Heinrich' Hałucha and done in Sound Division Studio, Warsaw, Poland. Guest solo part to the Leash track was recorded by Jacek Hiro. Shortly afterwards Iron decided to leave the band, replaced by an Artur 'Xan' Grabarczyk.

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".

List of gear nomenclature

Addendum

The addendum is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard pitch circle or pitch line; also, the radial distance between the pitch diameter and the outside diameter.

Addendum angle

Addendum angle in a bevel gear, is the angle between elements of the face cone and pitch cone.

Addendum circle

The addendum circle coincides with the tops of the teeth of a gear and is concentric with the standard (reference) pitch circle and radially distant from it by the amount of the addendum. For external gears, the addendum circle lies on the outside cylinder while on internal gears the addendum circle lies on the internal cylinder.

Pressure Angle

Apex to back

Apex to back, in a bevel gear or hypoid gear, is the distance in the direction of the axis from the apex of the pitch cone to a locating surface at the back of the blank.

Back angle

The back angle of a bevel gear is the angle between an element of the back cone and a plane of rotation, and usually is equal to the pitch angle.

Boolean-valued function

A boolean-valued function (sometimes called a predicate or a proposition) is a function of the type f : X → B, where X is an arbitrary set and where B is a boolean domain, i.e. a generic two-element set, (for example B = {0, 1}), whose elements are interpreted as logical values, for example, 0 = false and 1 = true.

In the formal sciences, mathematics, mathematical logic, statistics, and their applied disciplines, a boolean-valued function may also be referred to as a characteristic function, indicator function, predicate, or proposition. In all of these uses it is understood that the various terms refer to a mathematical object and not the corresponding semiotic sign or syntactic expression.

In formal semantic theories of truth, a truth predicate is a predicate on the sentences of a formal language, interpreted for logic, that formalizes the intuitive concept that is normally expressed by saying that a sentence is true. A truth predicate may have additional domains beyond the formal language domain, if that is what is required to determine a final truth value.
