Frank Nasworthy
Frank Nasworthy is notable in the history of skateboarding for introducing polyurethane wheel technology to the sport in the early 1970s. After graduating from Annandale High School in Northern Virginia in 1967, Nasworthy attended Virginia Tech for a year. Back with his family for the summer of 1970, he visited a plastics factory in Purcellville called Creative Urethane, owned by a friend’s father. The factory had experimented with a polyurethane roller skate wheel that was sold to Roller Sports Inc., which supplied wheels for rental skates at roller rinks. The rationale was that a softer wheel with improved grip would help novice roller skaters, but the wheel was largely rejected by roller skaters who favored the hard steel wheels that allowed for faster speeds on the wooden floors of the roller rinks. Up to this point, skateboards had also been manufactured with either the same steel wheels as rollerskates, or out of a clay composite – a combination of plastic, paper, and fine ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and Polyurethane laminate, PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as Copolymer#Alternating copolymers, alternating copolymers. Both the isocy ...

Skateboarding Equipment
Skateboarding is an action sport originating in the United States that involves riding and performing tricks using a skateboard, as well as a recreational activity, an art form, an entertainment industry job, and a method of transportation. Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue, with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding would be represented at the 2020 Summer Olympics in Tokyo, for both male and female teams. Since the 1970s, skateparks have been constructed specifically for use by skateboarders, freestyle BMXers, aggressive skaters, and more recently, scooters. However, skateboarding has become controversial in areas in which the activity, although illegal, has damaged curbs, stoneworks, steps, benches, plazas, and parks.

Freestyle skateboarding (or freestyle) is one of the oldest styles of skateboarding and was intermittently popular from the 1960s until the early 1990s, when the final large-scale professional freestyle skateboarding competition was held. Description The emphasis in freestyle is technical flat ground skateboarding. Often a freestyler will need little more than a board and a smooth, flat surface. Music and choreography have always been an essential part of the professional freestyle routine. History 1950s and 1960s Freestyle in the 1950s was created by members of the surfing culture who sought an alternative during times when conditions were not conducive to surfing—surfers would imitate their water-based maneuvers on skateboards when ocean conditions were poor. In the 1960s, many freestyle tricks were derived from gymnastics and dancing. 1970s and 1980s The following two decades were defined by a progression towards technical, fluid, and more creative routines.

Bearing (mechanical)
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may ''prevent'' a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts. Rotary bearings hold rotating components such as shafts or axles within mechanical systems, and transfer axial and radial loads from the source of the load to the structure supporting it. The simplest form of bearing, the ''plain bearing'', consists of a shaft rotating in a hole. Lubrication is used to reduce friction. In the ''ball bearing'' and ''roller bearing'', to reduce sliding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skateboard
A skateboard is a type of sports equipment used for skateboarding. They are usually made of a specially designed 7-8 ply maple plywood deck and polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboarder moves by pushing with one foot while the other foot remains balanced on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by simply standing on the deck while on a downward slope and allowing gravity to propel the board and rider. If the rider's leading foot is their right foot, they are said to ride "goofy". The two main types of skateboards are the longboard and the shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding started in California in the 1950s. The first skateboards were made from roller skates attached to a board. Skateboarding gained in popularity because of surfing: in fact, skateboarding ...
