Bridge Design Process In order to begin we must start our design process with the first step. We have to identify the need. The scenario is that we need to connect two pieces of land or structure so that a car must be able to pass through it. In this project we are to design and construct a bridge for a matchbox car. The bridge must be made of balsa wood and glue only. It must support its own weight‚ the load of the matchbox car‚ and additional weights that will be added. Next we must

Truss Bridge Physics 141 Robin Hoffmeister There is many reason that we need bridges in every day of our life‚ from sufficient means to pass over a roadway‚ waterway‚ railway‚ or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you would think of the physics that is involved in putting one together or the kind of force the bridge can actually

Popsicle-Stick Bridge The goal: to build the strongest possible bridge to take a matchbox car‚ using wooden popsicle sticks. Constraints: The bridge must span a 55cm gap No more than 100 popsicle sticks may be used The sticks may not be cut Only white glue may be used Construction paper may be used for the deck only The test load is applied to a 4cm-wide section at the top of the arch. The test jig looks like this: (Well-built bridges can support over

Bridge Write Up The problem that we have is we need to find a bridge that will fill a gap that is 12" long‚ and 2.5" wide. Our objective is to build a bridge that can hold up to 2.5kg at the most. The bridge must have a length at least 3inches‚ and a width of 2.5inches. Some constraints that we have are no more than 10% of the bridge may consist of "bulky" members made from two pieces of balsa wood. We can only use 15 pieces of balsa wood‚ and if we use string it has to be attached in a simple

The Anzac Bridge was first opened in 1995 was designed by Ken Wheeler from the RTA and took 6 years to build by the company Baulderstone Hornibrook. It is cable stayed bridge with a semi fan arrangement of the cables. It was built to replace the Glebe Island Bridge due to the bridge being unable to cope with large amounts of traffic. The Anzac Bridge was designed as a motorway to ease congestion and allow my traffic to flow through the bridge as well as including pedestrian paths and a bicycle path

The collapse of the 1940 Tacoma Narrows Bridge stunned everyone‚ especially engineers. How could the most "modern" suspension bridge‚ with the most advanced design‚ suffer catastrophic failure in a relatively light wind? The State of Washington‚ the insurance companies‚ and the United States government appointed boards of experts to investigate the collapse of the Narrows Bridge. The Federal Works Administration (FWA) appointed a 3-member panel of top-ranking engineers: Othmar Amman‚ Dr. Theodore

London Bridge The London Bridge is probably the most famous bridge ever built. After being in songs and being rebuilt a number of times the London Bridge is also one of the oldest bridges. The first London Bridge was built by Romans sometime after 43 AD and some of its wooden remains have been uncovered on the north side of the river. During its life the wooden structure was renewed several times‚ and it was probably to this earliest bridge that the nursery rhyme ‘London Bridge is falling
