Popsicle Stick Bridge

Fun stuff.

                                Arch Bridge

 The bridge I made was an  arch bride model which consisted of less then 100 Popsicle sticks.I selected this bride fro my project work for different reason.Arch bridge is one of the oldest big structure design in the human civilization and and also do not really proper methods and expenses it is also Strong and can carry a lot of weight and was first started in 2nd millennium BC in Mesopotamian brick architecture and their systematic use started with Ancient Roman who were the first to apply the technique to a wide range of structures.As the bridge is arch in structure that spans a space while supporting weight. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A a long bridge may be made from a series of arches, although other more economical structures are typically used today.An arch bridge is a bridge with abutments at each end shaped as a curved arch.The deck of an arch bridge can be curved upside downside or may be straight horizontal arch bridge are used in water bodies as the water flow underneath.Arch brides are not so much long. The longest one the Chaotianmen Bridge which spans the Yangtze River in Chongqing, China, is the world’s longest arch bridge, opened on April 29, 2009. It has a main span of 552 meters (1,811 ft) and a total length of 1,741 m (5,712 ft) .Many modern bridges, made of steel or reinforced concrete, often bear some of their load by tension within their structure. This reduces or eliminates the horizontal thrust against the abutments and allows their construction on weaker ground. Structurally and analytically they are not true arches but rather a Beam. A modern evolution of the arch bridge is the long-span through arch bridge. This has been made possible by the use of light materials that are strong in tension such as steel, reinforced concrete, and post-tensioned concrete.
Beam.A beam is a structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the beam as a result of the external loads, own weight, span and external reactions to these loads is called a bending moment.
