Wear is related to interactions between surfaces and specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface.
In materials science, wear is erosion or sideways displacement of material from its "derivative" and original position on a solid surface performed by the action of another surface.
Wear of metals occurs by the plastic displacement of surface and near-surface material and by the detachment of particles that form wear debris. This process may occur by contact with other metals, nonmetallic solids, flowing liquids, or solid particles or liquid droplets entrained in flowing gasses.
Wear can also be defined as a process where interaction between two surfaces or bounding faces of solids within the working environment results in dimensional loss of one solid, with or without any actual decoupling and loss of material. Aspects of the working environment which affect wear include loads and features such as unidirectional sliding, reciprocating, rolling, and impact loads, speed, temperature, but also different types of counter-bodies such as solid, liquid or gas and type of contact ranging between single phase or multiphase, in which the last multiphase may combine liquid with solid particles and gas bubbles.
A jibe (US) or gybe (Britain) is a sailing maneuver whereby a sailing vessel reaching downwind turns its stern through the wind, such that the wind direction changes from one side of the boat to the other. For square-rigged ships, this maneuver is called wearing ship.
In this maneuver, the mainsail will cross the center of the boat while the jib is pulled to the other side of the boat. If the spinnaker is up, the pole will have to be manually moved to the other side, to remain opposite the mainsail. In a dinghy, raising the centerboard can increase the risk of capsizing during what can be a somewhat violent maneuver, although the opposite is true of a dinghy with a flat, planing hull profile: raising the centerboard reduces heeling moment during the manouevre and so reduces the risk of capsize.
The other way to change the side of the boat that faces the wind is turning the bow of the boat into, and then through, the direction of the wind. This operation is known as tacking or coming about. Tacking more than 180° to avoid a jibe is sometimes referred to as a 'chicken jibe'.
Wear is the erosion of material from a solid surface by the action of another material.

Girlfriends is an American situation comedy that premiered on September 11, 2000, on UPN and aired on UPN's successor network, The CW, before being abruptly cancelled in 2008. The final episode aired on February 11, 2008. When Girlfriends returned in fall 2007 for its eighth season, it became the longest-running live-action sitcom on network television that was on air that fall 2007.
It was one of the highest-rated scripted shows on television among African-American adults 18-34, including its spin-off The Game.
Production
The series debuted on UPN on Monday September 11, 2000. After airing for several years on the network at 9/8C on Mondays, The CW moved Girlfriends to Sundays at 8/7C. The ratings plummeted. On October 9, 2006, Girlfriends, along with The CW's other African-American programs, moved back to Mondays. At this point, Girlfriends returned to its original time slot.
While UPN was still airing new episodes of Girlfriends, the network also began airing reruns five days per week. When the show moved to The CW network after UPN merged with The WB network, MyNetwork TV (which was created to take over UPN's former affiliate stations) picked up the rights to air reruns of Girlfriends, although they eventually discontinued this. WE tv, a network with primarily women's programming, later acquired exclusive rights to air the limited-release episodes on Sundays and exercised an option to not allow broadcast television networks re-broadcast rights to these reruns.
Girlfriends (Hangul: 걸프렌즈; RR: Gyeolpeurenjeu) is a 2009 South Korean romantic comedy film starring Kang Hye-jung, Han Chae-young, Huh E-jae and Bae Soo-bin.
It is based on the 2007 chick lit novel of the same title by Lee Hong, which won the 31st Writer of Today Award.
Plot
29-year-old Song-yi (Kang Hye-jung) starts dating her handsome co-worker Jin-ho (Bae Soo-bin). But when she suspects Jin-ho might be cheating on her, she sets out to meet the "other woman," only to learn that he has not one, but two, other "girlfriends": Jin (Han Chae-young), Jin-ho's first love, is a sexy and successful party planner, while Bo-ra (Huh E-jae) is a fearless, young college student. On one hand, Song-yi wants to keep Jin-ho all to herself, but strangely enough, she grows close to the two other women and their similar taste in men becomes the basis of a great friendship.
Cast
"Girlfriends" is the eighth episode of the HBO comedy series Flight of the Conchords. This episode first aired in the United States on Sunday, August 5, 2007.
Plot synopsis
Jemaine has his eye on a woman that works at the bakery. He wants Bret to go in the shop with him but Bret is reluctant because he doesn't like croissants. Eventually Jemaine convinces him to be his 'wingman'. While speaking to the woman and her colleague, Jemaine tries speaking a bit of French and they launch into a 1960s French style music video singing "Foux Du Fafa".
Later, on a double date at a nightclub, Jemaine is having trouble getting Lisa, the woman he liked at the croissant shop, interested in him. He convinces Bret to swap partners, but has no better luck with Felicia. Meanwhile Bret is uncomfortable with Lisa's aggressive advances.
At a band meeting Jemaine tells Murray about their new 'girlfriends'. At first a concerned Murray tells them that he thinks bands shouldn't have girlfriends, citing Wham! as an example of a successful band that followed that principle. But then he interrogates the guys for the juicy details. He then tells them that he has some good news. He has met A.J. Jones, supposedly the brother of Quincy Jones, who has sold him a high-end stereo system for $50.
