For many years people have been trying to make the best bridges in the world through length, width, height and even its height. But on top of this they try and make it as cheap as possible and also the easiest way possible. This is through the use of engineers. In this report I have been trying to construct a pasta bridge with pasta and pva glue. This bridge was staked with weights to find its strength and its breaking point. We found out that this bridge took 6kg and broke in its centre because this was the weakest construct of the bridge because the lack of its support in that area. In the end this bridge came second to Rowans that took 18 kg.

The author would like to acknowledge the teacher for all her effort she has put into teaching our class even though our normal teacher is sick. I would also like to acknowledge my parents for always showing support towards my studies in school

In this report there deals with the problems that bridges have been constructed in the last 3000 years to deal with problems that they have in counted as well as what they have done to overcome this problems. Here we so what we can accomplish with pasta. In this report there are a bunch of formula which is explained in the nomenclature of this report. In this I have used pasta and PVA glue to construct my bridge. History and society

Beam bridges
In the 5th century BC Herodotus a Greek historian wrote about a multi-span beam bridge. The span of each beam was 1.52m long but covered a distance of 200m with 100 stone piers that were linked with spate beams Early beam bridges were made of would but that changed because of termites and rotting 55 BC Julius Caesar built a 550m long beam bridge of wood. It had 50 spans and was in construction for 10 days 1570 Andrea Palladio an Italian architect developed a truss girder bridge. He got the idea from the timber roof trusses of a gothic church Early 19th century James Warren and English engineer created a truss girder bridge that would be used by railway engineers. In 1820 Ithiel Town in America developed a truss girder bridge for its modern day use. It contained criss-cross diagonals. This was good for light traffic but not strong enough for the railway because a lack of a truss built from triangles. The wooden trusses which were designed by William Howe in 1840 as well as Caleb and Thomas Pratt in 1844 let Ithiel Towns’ bridge be used for railway. Squire Whipple created the iron truss in 1847 which was still used in the 20th century. He also developed a way to find out the force in each member of a truss. Through him we can now determine how to build safer and more cost effective bridges 1849 Robert Stephenson an English engineer created the Bowstring Girder. The design consists of an arch that looks like a bow and a horizontal tie which looked like a string. It is a beam bridge that contains a support at both ends. This beam bridge like all does not place any lateral thrust on its supports. He created this bridge for his High-Level Bridge to cross the River Tyne in Newcastle. There are six pans which are 38m long....
