Funicular Curve
In architecture, the funicular curve (also funicular polygon, funicular shape, from the , "of rope") is an approach used to design the compression-only structural forms (like masonry arches) using an equivalence between the rope with hanging weights and standing arch with its load. This duality was noticed by Robert Hooke in 1675 ("as hangs the flexible line, so, but inverted, will stand the rigid arch"). If the hanging rope carries just its own weight (in this case it is usually called a "chain" and is equivalent to a free-standing arch with no external load), the resulting curve is a catenary. In graphic statics, a ''funicular polygon'' is a graphic method of finding out the line of action for a combination of forces applied to a solid body at different points, a complement to the force polygon used to obtain the value and direction of the resultant force. Both polygons were introduced by Pierre Varignon (''Nouvelle Mecanique ou Statique'', 1725) and became the basis of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analogy Between An Arch And A Hanging Chain And Comparison To The Dome Of St Peter's Cathedral In Rome
Analogy is a comparison or correspondence between two things (or two groups of things) because of a third element that they are considered to share. In logic, it is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction. It is also used where at least one of the premises, or the conclusion, is general rather than particular in nature. It has the general form ''A is to B as C is to D''. In a broader sense, analogical reasoning is a cognitive process of transferring some information or meaning of a particular subject (the analog, or source) onto another (the target); and also the linguistic expression corresponding to such a process. The term analogy can also refer to the relation between the source and the target themselves, which is often (though not always) a similarity, as in the biological notion of analogy. Analogy plays a significant role in human thought processes. It has been argued that analogy lies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resultant Force
In physics and engineering, a resultant force is the single force and associated torque obtained by combining a system of forces and torques acting on a rigid body via vector addition. The defining feature of a resultant force, or resultant force-torque, is that it has the same effect on the rigid body as the original system of forces. Calculating and visualizing the resultant force on a body is done through computational analysis, or (in the case of sufficiently simple systems) a free body diagram. The point of application of the resultant force determines its associated torque. The term ''resultant force'' should be understood to refer to both the forces and torques acting on a rigid body, which is why some use the term ''resultant force–torque''. The force equal to the resultant force in magnitude, yet pointed in the opposite direction, is called an equilibrant force. Illustration The diagram illustrates simple graphical methods for finding the line of application of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sagrada Família
The Basílica i Temple Expiatori de la Sagrada Família, otherwise known as Sagrada Família, is a church under construction in the Eixample district of Barcelona, Catalonia, Spain. It is the largest unfinished Catholic church in the world. Designed by the Catalans, Catalan architect Antoni Gaudí (1852–1926), in 2005 his work on Sagrada Família was added to an existing (1984) UNESCO World Heritage Site, "Works of Antoni Gaudí". On 7 November 2010, Pope Benedict XVI consecrated the church and proclaimed it a minor basilica. On 19 March 1882, construction of Sagrada Família began under architect Francisco de Paula del Villar y Lozano, Francisco de Paula del Villar. In 1883, when Villar resigned, Gaudí took over as chief architect, transforming the project with his architectural and engineering style, combining Gothic architecture, Gothic and curvilinear Art Nouveau forms. Gaudí devoted the remainder of his life to the project, and he is buried in the church's crypt. At ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Church Of Colònia Güell
The Church of Colònia Güell (, ) is an unfinished work by Antoni Gaudí Antoni Gaudí i Cornet ( , ; ; 25 June 1852 – 10 June 1926) was a Catalans, Catalan architect and designer from Spain, widely known as the greatest exponent of Catalan ''Modernisme''. Gaudí's works have a style, with most located in Barc .... It was built as a place of worship for the people on a hillside in a manufacturing area in Santa Coloma de Cervelló, near Barcelona (Catalonia, Spain). Colònia Güell was the brainchild of Count Eusebi de Güell; who enlisted the help of architect Antoni Gaudí in 1898. However, work was not started until 1908, 10 years after commission. The plan for the building consisted of constructing two naves, an upper and a lower, two towers, and one forty-meter-high central dome. In 1914, the Güell family halted construction due to the death of Count Güell. At the time, the lower nave was almost complete so between the years of 1915 and 1917, it was completed and ...
