Beam

Beam may refer to:

BEAM

Beam (nautical)

The beam of a ship is its width at the widest point as measured at the ship's nominal waterline. The beam is a bearing projected at right-angles from the fore and aft line, outwards from the widest part of ship. Beam may also be used to define the maximum width of a ship's hull, or maximum width plus superstructure overhangs.

Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at expense of reserve stability in the event of a capsize, where more energy is required to right the vessel from its inverted position.

Typical values

Typical length-to-beam ratios for small sailboats are from 2:1 (dinghies to trailerable sailboats around 20 ft or 6 m) to 5:1 (racing sailboats over 30 ft or 10 m).

Large ships have widely varying beam ratios, some as large as 20:1.

Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a coracle has a ratio of almost 1:1 – it is nearly circular.

Formula

The beam of many monohull vessels can be calculated using the following formula:

Beam (structure)

A beam is a structural element that is capable of withstanding load primarily by resisting against bending. The bending force induced into the material of the beam as a result of the external loads, own weight, span and external reactions to these loads is called a bending moment. Beams are characterized by their profile (shape of cross-section), their length, and their material.

Beams are traditionally descriptions of building or civil engineering structural elements, but smaller structures such as truck or automobile frames, machine frames, and other mechanical or structural systems contain beam structures that are designed and analyzed in a similar fashion.

Overview

Historically beams were squared timbers but are also metal, stone, or combinations of wood and metal such as a flitch beam. Beams generally carry vertical gravitational forces but can also be used to carry horizontal loads (e.g., loads due to an earthquake or wind or in tension to resist rafter thrust as a tie beam or (usually) compression as a collar beam). The loads carried by a beam are transferred to columns, walls, or girders, which then transfer the force to adjacent structural compression members. In light frame construction joists may rest on beams.

Originality

Originality is the aspect of created or invented works by as being new or novel, and thus can be distinguished from reproductions, clones, forgeries, or derivative works. An original work is one not received from others nor one copied from or based upon the work of others.. It is a work created with a unique style and substance. The term "originality" is often applied as a compliment to the creativity of artists, writers, and thinkers. The idea of originality as we know it was invented by Romanticism, with a notion that is often called romantic originality.

The concept of originality is culturally contingent. It became an ideal in Western culture starting from the 18th century. In contrast, at the time of Shakespeare it was common to appreciate more the similarity with an admired classical work, and Shakespeare himself avoided "unnecessary invention".

Originality in law

In law, originality has become an important legal concept with respect to intellectual property, where creativity and invention have manifest as copyrightable works. In the patent law of the United States and most other countries, only original inventions are subject to protection. In addition to being original, inventions submitted for a patent must also be useful and nonobvious.

Original (Cir.Cuz song)

"Original" is a song performed by Norwegian pop duo Cir.Cuz featuring vocals from Emila. It was released on 8 December 2014 as a digital download in Norway. The song peaked at number 28 on the Norwegian Singles Chart.
