What was the name of the person who invented the first screw?

In antiquity, the screw was first used as part of the screw pump of Sennacherib, King of Assyria, for the water systems at the Hanging Gardens of Babylon and Nineveh in the 7th century BC. The screw was later described by the Greek mathematician Archytas of Tarentum (428 - 350 BC). By the 1st century BC, wooden screws were commonly used throughout the Mediterranean world in devices such as oil and wine presses. Metal screws used as fasteners did not appear in Europe until the 1400s. In 1770, English instrument maker, Jesse Ramsden (1735-1800) invented the first satisfactory screw-cutting lathe. The British engineer Henry Maudslay (1771-1831) patented a screw-cutting lathe in 1797; a similar device was patented by David Wilkinson in the United States in 1798. In 1908, square-drive screws were invented by Canadian P. L. Robertson, becoming a North American standard. In the early 1930s, the Phillips head screw was invented by Henry F. Phillips.


Where was the steel manufactured for the Peace Bridge?

Peace Bridge is a pedestrian bridge, designed by Spanish architect Santiago Calatrava, that accommodates both pedestrians and cyclists crossing the Bow River in Calgary, Alberta, Canada. The bridge is open for use as of March 24, 2012.The bridge was built by The City of Calgary to connect the southern Bow River pathway and Downtown Calgary with the northern Bow River pathway and the community of Sunnyside. This connection was designed to accommodate the increasing number of people commuting to and from work and those utilizing Calgary's pathways.The bridge is reportedly used by 6000 people a day and has ranked among the top 10 architectural projects in 2012 and among the top 10 public spaces of 2012.[1][2]The design follows strict requirements with no piers in the water (in an effort to minimize the ecological footprint) and restricted height (due to the vicinity of the City/Bow River Heliport).The bridge has also been designed to:Withstand Calgary's one-in-100 year flood cycleMeet a minimum 75 year life spanAllow barrier free access for people of all mobility typesProvide comfort and security through lighting[3]As such, the bridge is a departure from Calatrava's usual designs, which are typically asymmetric shapes anchored by high masts.[4]Another atypical element is the colour, while most of Calatrava's designs are white, the Peace Bridge features a red and white pattern (Red and white are the colours in both the Flag of Canada and the Flag of Calgary).Features Helical steel structure with a glass roof (850-metric-tonne steel)A width of 6.3 metres - double the width of other pedestrian bridges in the areaSegregated bicycle and pedestrian trafficLighting for night time useMaterials used Steel for the archesReinforced concrete abutments & deckDimensions Span length: Tube Girder 126 meters (413 ft)Total length: Out to Out 130.6 meters (428 ft)Total width: 8 meters (26 ft)Total height: 5.85 meters (19.2 ft)Inside width: 6.2 meters (20 ft) (3.7 meters (12 ft) for pedestrian and 2.5 meters (8.2 ft) for cycleway) [5]Cost[edit]Funding for the Peace Bridge was provided by The City's Capital Budget. For the Transportation department, targeted expenditures of capital are directed by the Transportation Infrastructure Investment Program (TIIP), which defines the priority and timing of major infrastructure construction projects. This program emphasizes pedestrian and cycling in high-density areas where these modes are more efficient at moving people, supporting land use and lessening environmental impacts. [6] As of February 2012, the approximate costs were:Construction: $17.995 millionArchitectural and structural design, specialized engineering and quality assurance: $3.9 millionProject administration and contingency: $2.6 million[7]History[edit]On September 8, 2008, Calgary City Council approved report LPT2008-49 which set aside $25 million for the Pedestrian Gateways project for two bridges across the Bow River: one west of Prince's Island Park and one at the west of St. George's Island. The decision directed Administration to design and build one bridge and develop a concept design for a second one.[citation needed]Construction started in March 2010. A temporary structure was built immediately upstream from the bridge location and served as a place to assemble the bridge before moving it to its final position.The tubular bridge was manufactured in Spain and shipped to Calgary. Assembly of the bridge pieces started in Fall 2010 and the bridge was moved across the Bow River in November 2011.[8][9]During routine weld inspection, it was discovered that some of the welds did not comply with quality standards. As a result, the city hired an independent inspection company to do a more thorough inspection of the welds completed in Spain.[10]The added inspections, red flags about the steel work's esthetics, weld repairs, and issues with damaged concrete slabs all contributed to multiple delays in the opening of the bridge. [11] [12] [13]The bridge, originally supposed to be opened in the fall of 2010, opened to the public on March 24, 2012.[14]The temporary bridge built to support the construction in May 2010Temporary bridge completed in June 2010Assembly of the segments in Calgary
