Kirkaldy Testing Museum
The Kirkaldy Testing Museum is a museum in Southwark, south London, England, in David Kirkaldy's former testing works. It houses Kirkaldy's huge testing machine, and many smaller more modern machines. It is open on the first Sunday of each month. The building at 99 Southwark Street became a listed building in 1971, and was promoted to Grade II* in June 2014. Background Kirkaldy was born in Dundee in 1820, and educated at Edinburgh University. He worked at Napier shipbuilding works from 1843, where he became Chief Draughtsman and Calculator. He left in 1861 and over the next two and a half years studied existing mechanical testing methods and designed his own testing machine. William Fairbairn had pioneered tensile strength measurement as well as assessing creep and fatigue on large structures as well as small. Entirely at his own expense, Kirkaldy commissioned his machine from the Leeds firm of Greenwood & Batley, closely supervising its production. Aggrieved over the slow r ...

Southwark
Southwark ( ) is a district of Central London situated on the south bank of the River Thames, forming the north-western part of the wider modern London Borough of Southwark. The district, which is the oldest part of South London, developed due to its position at the southern end of the early versions of London Bridge, the only crossing point for many miles. London's historic core, the City of London, lay north of the Bridge and for centuries the area of Southwark just south of the bridge was partially governed by the city. By the 12th century Southwark had been incorporated as an ancient borough, and this historic status is reflected in the alternative name of the area, as Borough. The ancient borough of Southwark's river frontage extended from the modern borough boundary, just to the west of by the Oxo Tower, to St Saviour's Dock (originally the mouth of the River Neckinger) in the east. In the 16th century, parts of Southwark became a formal City ward, Bridge Without. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Microscopy
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ac ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag Inclusion (mineral), inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to structural failure, failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welding, forge welded, but is more difficult to welding, weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is Carbon steel#Mild or low-carbon steel, mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Havilland Comet
The de Havilland DH.106 Comet was the world's first commercial jet airliner. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large square windows. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. Within a year of entering airline service, problems started to emerge, three Comets being lost within twelve months in highly publicised accidents, after suffering catastrophic in-flight break-ups. Two of these were found to be caused by structural failure resulting from metal fatigue in the airframe, a phenomenon not fully understood at the time; the other was due to overstressing of the airframe during flight through severe weather. The Comet was withdrawn from service and extensively tested. Design and cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BOAC Flight 781
BOAC Flight 781 was a scheduled British Overseas Airways Corporation (BOAC) passenger flight from Singapore to London. On 10 January 1954, a de Havilland Comet passenger jet operating the flight suffered an explosive decompression at altitude and crashed, killing all 35 people on board. The aircraft, registered had taken off shortly before from Ciampino Airport in Rome, en route to Heathrow Airport in London, on the final leg of its flight from Singapore. After it exploded, the debris from the explosion fell into the sea near Elba Island, off the Italian coast. G-ALYP was the third Comet built. Its loss marked the second in a series of three fatal accidents involving the Comet in less than twelve months, all caused by structural failures; it followed the crash of BOAC Flight 783 near Calcutta, India, in May 1953, and was followed by the loss of South African Airways Flight 201 in April 1954, which crashed in circumstances similar to BOAC 781 after departing from Ciampino Airpor ...

Tay Bridge Disaster
The Tay Bridge disaster occurred during a violent storm on Sunday 28 December 1879, when the first Tay Rail Bridge collapsed as a North British Railway (NBR) passenger train on the Edinburgh to Aberdeen Line from Burntisland bound for its final destination of Dundee passed over it, killing all aboard. The bridge—designed by Sir Thomas Bouch—used lattice girders supported by iron piers, with cast iron columns and wrought iron cross-bracing. The piers were narrower and their cross-bracing was less extensive and robust than on previous similar designs by Bouch. Bouch had sought expert advice on wind loading when designing a proposed rail bridge over the Firth of Forth; as a result of that advice he had made no explicit allowance for wind loading in the design of the Tay Bridge. There were other flaws in detailed design, in maintenance, and in quality control of castings, all of which were, at least in part, Bouch's responsibility. Bouch died less than a year after the disast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accident Analysis
Accident analysis is carried out in order to determine the cause or causes of an accident (that can result in single or multiple outcomes) so as to prevent further accidents of a similar kind. It is part of ''accident investigation or incident investigation .'' These analyses may be performed by a range of experts, including forensic scientists, Forensic engineering#Forensic engineering, forensic engineers or health and safety advisers. Accident investigators, particularly those in the aircraft industry, are colloquially known as "tin-kickers". Health and safety and patient safety professionals prefer using the term "incident" in place of the term "accident". Its retrospective nature means that accident analysis is primarily an exercise of directed explanation; conducted using the theories or methods the analyst has to hand, which directs the way in which the events, aspects, or features of accident phenomena are highlighted and explained. Sequence Accident analysis is performed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festival Of Britain
The Festival of Britain was a national exhibition and fair that reached millions of visitors throughout the United Kingdom in the summer of 1951. Historian Kenneth O. Morgan says the Festival was a "triumphant success" during which people: Labour cabinet member Herbert Morrison was the prime mover; in 1947 he started with the original plan to celebrate the centennial of the Great Exhibition of 1851. However, it was not to be another World Fair, for international themes were absent, as was the British Commonwealth. Instead the 1951 festival focused entirely on Britain and its achievements; it was funded chiefly by the government, with a budget of £12 million. The Labour government was losing support and so the implicit goal of the festival was to give the people a feeling of successful recovery from the war's devastation, as well as promoting British science, technology, industrial design, architecture and the arts. The Festival's centrepiece was in London on the South Bank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skylon (tower)
The Skylon was a futuristic-looking, slender, vertical, cigar-shaped steel tensegrity structure located by the Thames in London, that gave the illusion of 'floating' above the ground, built in 1951 for the Festival of Britain. A popular joke of the period was that, like the British economy of 1951, "It had no visible means of support". Construction The Skylon was the "Vertical Feature" that was an abiding symbol of the Festival of Britain. It was designed by Hidalgo Moya, Philip Powell and Felix Samuely, and fabricated by Painter Brothers of Hereford, England, on London's South Bank between Westminster Bridge and Hungerford Bridge. The Skylon consisted of a steel latticework frame, pointed at both ends and supported on cables slung between three steel beams. The partially constructed Skylon was rigged vertically, then grew taller in situ. The architects' design was made structurally feasible by the engineer Felix Samuely who, at the time, was a lecturer at the Architec ...
