Wear And Tear
Wear and tear is damage that naturally and inevitably occurs as a result of normal wear or aging. It is used in a legal context for such areas as warranty contracts from manufacturers, which usually stipulate that damage from ''wear and tear'' will not be covered. Wear and tear is a form of depreciation, which is assumed to occur even when an item is used competently and with care and proper maintenance. For example, repeated impacts may cause stress to a hammer's head. This stress is impossible to prevent in the normal use of the tool for its designed task, and any attempt to avert it impedes its functionality. At the same time, it is expected that the normal use of a hammer will not break it beyond repair during a reasonable life cycle. If an object's restoration is impossible, it is regarded as consumable. Parts that are designed to wear inside a machine—e.g., bearings and O-rings—are intended to be replaced with new ones; consumables like paper, cardboard, fabrics, ...

Fabric
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, and different types of fabric. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: consumer textiles for domestic purposes and technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, while in technical textiles, functional properties are the priority. The durability of textiles is an important property, with common cotton or blend garments (such as t-shirts) able to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Life
A product's service life is its period of use in service. Several related terms describe more precisely a product's life, from the point of manufacture, storage, and distribution, and eventual use. Service life has been defined as "a product's total life in use from the point of sale to the point of discard" and distinguished from replacement life, "the period after which the initial purchaser returns to the shop for a replacement". Determining a product's expected service life as part of business policy ( product life cycle management) involves using tools and calculations from maintainability and reliability analysis. Service life represents a commitment made by the item's manufacturer and is usually specified as a median. It is the time that any manufactured item can be expected to be "serviceable" or supported by its manufacturer. Service life is not to be confused with '' shelf life'', which deals with storage time, or with technical life, which is the maximum period ...

Longevity
Longevity may refer to especially long-lived members of a population, whereas ''life expectancy'' is defined Statistics, statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year (in the case of Cohort (statistics), cohorts). Longevity studies may involve putative methods to extend life. Longevity has been a topic not only for the scientific community but also for writers of Hyperborei, travel, science fiction, and utopian novels. The legendary fountain of youth appeared in the work of the Ancient Greek historian Herodotus. There are difficulties in authenticating the longest human maximum life span, life span, owing to inaccurate or incomplete birth statistics. Fiction, legend, and folklore have proposed or claimed life spans in the past or future vastly longer than those verified by modern standards, and longevity narratives and unverif ...

Distressing
Distressing (or weathered look) in the decorative arts is the activity of making a piece of furniture or object appear aged and older, giving it a "weathered look". There are many methods to produce an appearance of age and wear. Distressing is viewed as a refinishing technique although it is the opposite of finishing in a traditional sense. In distressing, the object's finish is intentionally destroyed or manipulated to look less than perfect, such as with sandpaper or paint stripper. For example, the artisan often removes some but not all of the paint, leaving proof of several layers of paint speckled over wood grain underneath. This becomes the "finished" piece. Distressing has become a popular design style and decorative art form. The artisan attempts a Pastoral, rustic, attractive, one-of-a-kind appearance or vintage (design), vintage look. The final appearance is often called the patina. Distressing can be applied to a variety of surfaces and materials such as wood, glass ...

Tire
A tire (North American English) or tyre (Commonwealth English) is a ring-shaped component that surrounds a Rim (wheel), wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide Traction (engineering), traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, providing a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, designed to match the vehicle's weight and the bearing on the surface that it rolls over by exerting a pressure that will avoid deforming the surface. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tire tread, tread and a body. The tread provides Traction (engineering), traction while the body provides containment for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gunsmith
A gunsmith is a person who repairs, modifies, designs, or builds guns. The occupation differs from an armorer, who usually replaces only worn parts in standard firearms. Gunsmiths do modifications and changes to a firearm that may require a very high level of craftsmanship, requiring the skills of a top-level machinist, a very skilled woodworker, and even an engineer. Gunsmiths perform factory-level repairs and renovations to restore well-used or deteriorated firearms to new condition. They may make alterations to adapt sporting guns to better fit the individual shooter that may require extensive modifications to the firearm's stocks and metal parts. Repairs and redesigns may require fabrication and fitting of unavailable parts and assemblies constructed by smiths themselves. Gunsmiths may also renew metal finishes or apply decorative carvings or engravings to guns. Many gun shops offer gunsmithing service on the premises. Overview Gunsmiths may be employed in: * armories by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luthier
A luthier ( ; ) is a craftsperson who builds or repairs string instruments. Etymology The word ' is originally French and comes from ''luth'', the French word for "lute". The term was originally used for makers of lutes, but it came to be used in French for makers of most bowed and plucked stringed instruments such as members of the violin family (including violas, cellos, and double basses) and guitars. Luthiers, however, do not make harps or pianos; these require different skills and construction methods because their strings are secured to a frame. Craft The craft of luthiers, lutherie (rarely called "luthiery", but this often refers to stringed instruments other than those in the violin family), is commonly divided into the two main categories of makers of stringed instruments that are plucked or strummed and makers of stringed instruments that are bowed. Since bowed instruments require a bow, the second category includes a subtype known as a bow maker or archetier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
