Windscreen
The windshield (American English and Canadian English) or windscreen (Commonwealth English) of an aircraft, car, bus, motorbike, truck, train, boat or streetcar is the front window, which provides visibility while protecting occupants from the elements. Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of, typically, two curved sheets of glass with a plastic layer laminated between them for safety, and bonded into the window frame. Motorcycle windshields are often made of high-impact polycarbonate or acrylic plastic. Usage Windshields protect the vehicle's occupants from wind and flying debris such as dust, insects, and rocks, and provide an aerodynamically formed window towards the front. UV coating may be applied to screen out harmful ultraviolet radiation. However, this is usually unnecessary since most auto windshields are made from laminated safety glass. The majority of UV-B is absorbed by the glass itself, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poly(methyl Methacrylate)
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Walcast, Hesalite, Plexiglas, Acrylite, Lucite, PerClax, and Perspex, among several others ( see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. It is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as ''acrylic glass''. History The first acrylic acid was created in 1843. Methacrylic acid, derived from acrylic acid, was formulated in 1865. The reaction between methacrylic acid and methanol results in the ester methyl methacrylate. It was developed in 1928 in several different la ...

Toughened Glass
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to shatter into small granular chunks instead of splintering into large jagged shards as ordinary annealed glass does. These smaller, granular chunks are less likely to cause deep penetration when forced into the surface of an object (e.g. by gravity, by wind, by falling onto them, etc.) compared to larger, jagged shards because the reduction in both the mass and the maximum dimension of a glass fragment corresponds with a reduction in both the momentum and the penetration depth of the glass fragment. Tempered glass is used for its safety and strength in a variety of applications, including passenger vehicle windows (apart from windshield), shower doors, aquariums, architectural glass doors ...

Glass
Glass is an amorphous (non-crystalline solid, non-crystalline) solid. Because it is often transparency and translucency, transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass are named after the material, e.g., a Tumbler (glass), "glass" for drinking, "glasses" for vision correction, and a "magnifying glass". Glass is most often formed by rapid cooling (quenching) of the Melting, molten form. Some glasses such as volcanic glass are naturally occurring, and obsidian has been used to make arrowheads and knives since the Stone Age. Archaeological evidence suggests glassmaking dates back to at least 3600 BC in Mesopotamia, Ancient Egypt, Egypt, or Syria. The earliest known glass objects were beads, perhaps created accidentally during metalworking or the production of faience, which is a form of pottery using lead glazes. Due to its ease of formability int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henry Ford
Henry Ford (July 30, 1863 – April 7, 1947) was an American Technological and industrial history of the United States, industrialist and business magnate. As the founder of the Ford Motor Company, he is credited as a pioneer in making automobiles affordable for middle-class Americans through the system that came to be known as Fordism. In 1911, he was awarded a patent for the transmission mechanism that would be used in the Ford Model T and other automobiles. Ford was born in a farmhouse in Springwells Township, Michigan, and left home at the age of 16 to find work in Detroit. It was a few years before this time that Ford first experienced automobiles, and throughout the later half of the 1880s, he began repairing and later constructing engines, and through the 1890s worked with DTE Electric Company, a division of Edison Electric. He founded the Ford Motor Company in 1903 after prior failures in business, but success in constructing automobiles. The introduction of the Ford M ...

Laminated Glass
Laminated glass is a type of safety glass consisting of two or more layers of glass with one or more thin polymer interlayers between them which prevent the glass from breaking into large sharp pieces. Breaking produces a characteristic "spider web" cracking pattern (radial and concentric cracks) when the impact is not enough to completely pierce the glass. Laminated glass is used for architecture, glazing, automobile safety, photovoltaic, UV protection, and artistic expression. The most common use of laminated glass is automobile windshields and skylight glazing. In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtain walls, and windows. Laminated glass is also used to increase the sound insulation rating of a window, because it significantly improves sound attenuation compared to monolithic glass panes of the same thickness. The interlayer is typically of polyvinyl butyral (PVB), ethylene-vinyl ace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seal (mechanical)
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leak, leakage (e.g. in a wikt:pumping, pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets. The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications. A stationary seal may also be referred to as a 'packing'. Seal types: *Induction sealing or cap sealing *Sealant, Adhesive, sealant *Bodok seal, a specialized gas sealing washer for medical applications *Bonded seal, also known as Dowty Group, Dowty seal or Dowty washer. A type of Washer (hardware), washer with integral gasket, widely used to provide a seal at the entry point of a screw or bolt *Bridgman seal, a piston sealing mechanism that creates a high pressure reservoir from a lower pressure ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Hevea brasiliensis, Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to out ...

Reckless Driving
In United States law, reckless driving is a major moving violation related to aggressive driving that generally consists of driving a vehicle with willful or wanton disregard for the safety of persons or property. It is usually a more serious offense (law), offense than careless driving, improper driving, or driving without due care and attention, and is often punishable by fine (penalty), fines, imprisonment, or the suspension or revocation of one's driver's license. In Commonwealth of Nations, Commonwealth countries, the offense of dangerous driving applies. Reckless driving has been studied by psychologists who found that reckless drivers score high in risk-taking personality traits; however, no one cause can be assigned to the mental state. Depending on the jurisdiction, reckless driving may be defined by a particular mens rea, subjective mental state that is evident from the circumstances, or by particular driver actions regardless of mental state, or both.
