Wobbly-web Wheel
The wobbly-web wheel is a form of metal disc wheel where the disc is 'wobbled' into spokes. This provides a stiffer, lightweight wheel. Wobbly-web wheels are best known through their iconic use on Lotus cars, Lotus racing cars of the late 1950s and 1960s. Theory The theory of a disc wheel depends on their behaviour as a stressed skin structure. Their materials are assumed to be wikt:inextensible, inextensible, but flexibility, flexible. Such a skin is stiff against tensile loads in the plane of the skin, but flexible for loads perpendicular to it. A flat disc is thus strong for wikt:radial, radial loads in the plane of the disc and also for torques. It is flexible for cylindrical coordinate system, axial loads, perpendicular to the disc plane and also for nutation (engineering), nutating, wobble of the axle at an angle to the main axis. A coned disc also becomes stiff against axial loads, as the web is no longer purely perpendicular to the axis of the wheel. Unlike a flat dis ...

Light Alloy
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively '' optical radiation''. In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization. Its speed in vacuum, , is one of the fundamental constants of nature. All electromagnetic radiation exhibits some properties of both particles and waves. Si ...

Lightening Holes
Lightening holes are holes in structural components of machines and buildings used by a variety of engineering disciplines to make structures lighter. The edges of the hole may be flanged to increase the rigidity and strength of the component. The holes can be circular, triangular, elliptical, or rectangular and should have rounded edges, but they should never have sharp corners, to avoid the risk of stress risers, and they must not be too close to the edge of a structural component. Usage Aviation Lightening holes are often used in the aviation industry. This allows an aircraft to be as lightweight as possible, retaining the durability and airworthiness of the aircraft structure. Maritime Lightening holes have also been used in marine engineering to increase seaworthiness of the vessel. Motorsports Lightening holes became a prominent feature of motor racing in the 1920s and 1930s. Chassis members, suspension components, engine housings and even connecting rods were dril ...

Boxpok
A Boxpok is a steam locomotive wheel that gains its strength through being made of a number of box sections rather than having traditional solid spokes (the name is a variation on "box-spoke"). Being hollow, they allow better counterbalancing and stability than conventional drivers, which is important for fast locomotives. The Boxpok wheel was patented by General Steel Castings Corporation of Granite City, Illinois Illinois ( ) is a U.S. state, state in the Midwestern United States, Midwestern United States. It borders on Lake Michigan to its northeast, the Mississippi River to its west, and the Wabash River, Wabash and Ohio River, Ohio rivers to its .... Other wheels The Boxpok was the most common of the four disk wheels in use by US steam locomotive designers, the others being the Baldwin and Scullin. A fourth design, the Universal, was used in locomotive rebuilds. All vary slightly in appearance but are essentially the same in structure. The term "Boxpok" is al ...

Bulleid Firth Brown
The Bulleid Firth Brown wheel (BFB) was a locomotive wheel developed for the Southern Railway (UK), Southern Railway in the late 1930s. It was a disc wheel, in contrast to the usual spoked wheels in general use on British railways. The wheel was designed by Oliver Bulleid and developed by the steel company Firth Brown of Sheffield. Design The BFB comprises a single disc, with teardrop-shaped indentations to give rigidity, and lightening holes to reduce weight. The advantage over a spoked wheel is that a disc wheel carries the tyre (the metal hoop shrunk onto the wheel to provide contact with the rail) more efficiently; spoked wheels are prone to shrink over time, causing the tyre to work loose, whilst in a disc wheel this is less pronounced. Disc wheels also distribute the weight more evenly, reducing hammer blow on (and thus the damage to) the rail. In conventional spoked wheels, the tyre is shrunk onto the centre and then locked in place by a retaining 'Gibson ring' at the re ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, Fuel oil, oil or, rarely, Wood fuel, wood) to heat water in the locomotive's Boiler (power generation), boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its Steam locomotive components, cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a Tender (rail), tender coupled to it. #Variations, Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom of Great Britain an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullied Firth Brown Boxpok Wheel
Bullying is the use of force, coercion, hurtful teasing, comments, or threats, in order to abuse, aggressively dominate, or intimidate one or more others. The behavior is often repeated and habitual. One essential prerequisite is the perception (by the bully or by others) that an imbalance of physical or social power exists or is currently present. This perceived presence of physical or social imbalance is what distinguishes the behavior from being interpreted or perceived as ''bullying'' from instead being interpreted or perceived as '' conflict''. Bullying is a subcategory of aggressive behavior characterized by hostile intent, the goal (whether consciously or subconsciously) of addressing or attempting to "fix" the imbalance of power, as well as repetition over a period of time. Bullying can be performed individually or by a group, typically referred to as ''mobbing'', in which the bully may have one or more followers who are willing to assist the primary bully or who ...

Cosmos Engineering
Cosmos Engineering was a company that manufactured aero-engines in a factory in Fishponds, Bristol during World War I. Sir Roy Fedden, the company's principal designer, developed the 14-cylinder radial Mercury engine during this period. The company was taken over by the Bristol Aeroplane Company in 1920. Company origins In 1918 the Anglo-American company Cosmos bought Straker-Squire (also known as Brazil Straker), a car and bus manufacturing firm which had branched out into aircraft engine repair and manufacture. This began by first reconditioning, then substantially redesigning and re-manufacturing Curtiss OX-5 engines. Due to the quality of this work, they were the only company permitted to manufacture Rolls-Royce aircraft engines under licence, building Hawk and Falcon engines, major components for the Eagle engine and also 600 Renault 80hp 8Ca engines. Over 1,500 engines were produced in total. The company was one of the first to be brought under Admiralty control, and Fe ...

Roy Fedden
Sir Alfred Hubert Roy Fedden MBE, FRAeS (6 June 1885 – 21 November 1973) was an engineer who designed most of Bristol Engine Company's successful piston aircraft engine designs. Early life Fedden was born in the Bristol area to fairly wealthy and influential parents. His older brother was the artist Romilly Fedden. Fedden's family was the first in the area to own a car, an interesting parallel with fellow engine designer, Harry Ricardo. This early influence almost certainly led to his future career. Fedden attended Clifton College, but did not do well scholastically and was known primarily for sports. After leaving, he declined to enter the Army, and announced he would apprentice as an engineer. Apprenticeship His apprenticeship was completed in 1906, and he immediately designed a complete car. He managed to convince the local firm of Brazil Straker to hire him, and the design was produced as the successful Shamrock. He remained at Brazil Straker over the following years ...
