Los Angeles Motordrome
The Los Angeles Motordrome was a circular board track racing, wood board Motorsport, race track. It was located in Playa del Rey, California, and opened in 1910. In addition to automobile racing, it was used for motorcycle competition and aviation activities. The Motordrome was a scaled-up version of a bicycling velodrome, and was built by Jack Prince, a pre-eminent constructor of velodromes at the time. It was the first of numerous board tracks built for auto racing in the 1910s and 1920s. As an early example of a race track purpose-built for competition, it marked the first use of then-innovative safety features that later became common to most tracks. The Motordrome was highly successful, attracting many competitors and large crowds of paying spectators, but it lasted just three years. A fire destroyed the track in January 1913. Background The Motordrome was the brainchild of Hungarian people, Hungarian-born mechanical engineer Frederick Moskovics, who at the time w ...

Motordrome, California
Motordrome is an archaic placename in Los Angeles County, California. It designates a rail spur that existed in the 1910s on the Redondo Beach via Del Rey Line, named for the Los Angeles Motordrome race track and airfield. Motordrome station lay at an elevation of 7 feet (2 m). The coordinates for Motordrome preserved in the GNIS () place it near the present-day intersections of Jefferson Boulevard and Culver Boulevard, in what is now the Ballona Wetlands Ecological Reserve. Even though the racetrack was destroyed in a fire in 1913, and the rails were removed by 1918, the place name persisted on USGS survey maps until at least the 1930s. The Barnes Circus train partially derailed at Motordrome in 1914, injuring four.

Guard Rail
Guard rails, guardrails, railings or protective guarding, in general, are a boundary feature and may be a means to prevent or deter access to dangerous or off-limits areas while allowing light and visibility in a greater way than a fence. Common shapes are flat, rounded edge, and tubular in horizontal railings, whereas tetraform spear-headed or ball-finialled are most common in vertical railings around homes. Park and garden railings commonly in metalworking feature swirls, leaves, plate metal areas and/or Motif (visual arts), motifs particularly on and beside gates. High security railings (particularly if in flat metal then a type of palisade) may instead feature jagged points and most metals are well-suited to anti-climb paint. A handrail is less restrictive on its own than a guard rail and provides support. Public safety Many public spaces are fitted with guard rails as a means of protection against accidental falls.

Banked Turn
A banked turn (or banking turn) is a turn or change of direction in which the vehicle banks or inclines, usually towards the inside of the turn. For a road or railroad this is usually due to the roadbed having a transverse down-slope towards the inside of the curve. The bank angle is the angle at which the vehicle is inclined about its longitudinal axis with respect to the horizontal. Turn on flat surfaces If the bank angle is zero, the surface is flat and the normal force is vertically upward. The only force keeping the vehicle turning on its path is friction, or traction. This must be large enough to provide the centripetal force, a relationship that can be expressed as an inequality, assuming the car is driving in a circle of radius r: :\mu mg > . The expression on the right hand side is the centripetal acceleration multiplied by mass, the force required to turn the vehicle. The left hand side is the maximum frictional force, which equals the coefficient of friction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Shells
A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer usually created by an animal or organism that lives in the sea. Most seashells are made by mollusks, such as snails, clams, and oysters to protect their soft insides. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have decomposed or been eaten by another organism. A seashell is usually the exoskeleton of an invertebrate (an animal without a backbone), and is typically composed of calcium carbonate or chitin. Most shells that are found on beaches are the shells of marine mollusks, partly because these shells are usually made of calcium carbonate, and endure better than shells made of chitin. Apart from mollusk shells, other shells that can be found on beaches are those of barnacles, horseshoe crabs and brachiopods. Marine annelid worms in the family Serpulidae create shells which are tubes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. ''World Flora Online'' accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, and ''Plants of the World Online'' 126 species-rank taxa (113 species and 13 nothospecies), making it the largest genus among the conifers. The highest species diversity of pines is found in Mexico. Pines are widely species distribution, distributed in the Northern Hemisphere; they occupy large areas of boreal forest, but are found in many habitats, including the Mediterranean Basin, and dry tropical forests in southeast Asia and Central America. Wood from pine trees is one of the most extensively used types of timber, and some pines are widely used as Christmas trees. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reachin ...

Arc Lamp
An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light. It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th century. It continued in use in more specialized applications where a high intensity point light source was needed, such as searchlights and movie projectors until after World War II. The carbon arc lamp is now obsolete for most of these purposes, but it is still used as a source of high intensity ultraviolet light. The term is now used for gas discharge lamps, which produce light by an arc between metal electrodes through a gas in a glass bulb. The common fluorescent lamp is a low-pressure mercury arc lamp. The xenon arc lamp, which produces a high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Los Angeles Herald
The ''Los Angeles Herald'' or the ''Evening Herald'' was a newspaper published in Los Angeles in the late 19th and early 20th centuries. Founded in 1873 by Charles A. Storke, the newspaper was acquired by William Randolph Hearst in 1931. It merged with the '' Los Angeles Express'' and became an evening newspaper known as the '' Los Angeles Herald-Express''. A 1962 combination with Hearst's morning '' Los Angeles Examiner'' resulted in its final incarnation as the evening ''Los Angeles Herald-Examiner''.

Appealing to a mostly working-class audience during its 116 years of publication, the ''Herald'' evolved from a primary focus on agriculture to reporting extensively on Hollywood gossip and local scandal, reflecting the transformation of Los Angeles itself during the twentieth century.

AAA Contest Board
The AAA Contest Board was the motorsports arm of the American Automobile Association. The contest board sanctioned automobile races from 1904 until 1955, establishing American Championship car racing. Modern-day Indy car racing traces its roots directly to these AAA events. All of the races at the Indianapolis Motor Speedway during that time period were sanctioned by AAA, including the Indianapolis 500. AAA sanctioned the 1905 National Motor Car Championship, the first national championship for major auto racing. It resumed the National Championship in 1916, and again from 1920 to 1955. It also sanctioned the Vanderbilt Cup.White, GordonThe AAA Contest Board, Retrieved 2010-10-22 The AAA Contest Board dissolved and decided to focus strictly on helping the automobiling public as a result of the 1955 Le Mans disaster. History AAA was established in Chicago, Illinois on March 4, 1902. By June the same year, AAA also established the Racing Board. A. R. Pardington was appoint ...
