Truss

Edmond Liu My popsicle bridge is based on a truss design, which is a bridge design held up by a connected structure composed of many smaller pieces. In particular, my bridge is a variation of the Queen Post Truss Bridge, which has two central supporting posts to allow for a greater span allowing for larger contact points. (http://pghbridges.com/basics.htm) My design is modified to incorporate two extra posts towards the two contact points where the bridge rests on the desk, to increase the stability of the structure above the roadbed. The roadbed itself is made from two 34cm long beams, which are each…

Arch bridge, Truss bridge, Cantilever bridge, Cable-Stayed bridge, Beam bridge and Suspension bridge, All ranging with different designs. All of the different bridge designs are made to withstand a specific amount of weight. A bridge supports weight when the base of the bridge is made out of strong and good material to support the long span. Bridges can hold heavy loads because of the constant pulling and pushing force of each part of the bridge. This form of force is commonly known as…

For the purpose of this project we will be discussing mainly the truss bridge. A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. (john, 2013) A truss is assumed to comprise of members that are connected by means of pin joints, and which is supported at both ends by…

There are many different types of bridges. More specifically, there are many types of truss bridges. One popular truss bridge is the Golden Gate Bridge, which is located in San Francisco, California. This bridge is a Warren deck truss bridge because of the equal size of the diagonals and to contain both tension and compression (Types of bridges) and it has a Suspension, fixed and approach Spans because of the metal braced ribbed deck arch.(Golden Gate Bridge). Some other important features of…

Students must also follow directions and understand the prerequisite requirements associated with creating a truss bridge. This lesson plan meets these conditions because it leverages a variety of resources to assemble information about student learning as well as a wide range of appropriate assessment strategies to evaluate student progress. Students are required to learn technical drafting skill sets which will enable them to create orthographic views and achieve success with this lesson plan.…

This is a simple bridge because the ends of the girders are on top of the pier and abutments. The span of a girder bridge can go up to 1,000 feet. Truss bridges are bridges that are supported by trusses. The trusses are set in a triangular pattern. A truss bridge can have a span of over 1,000. Every truss is a triangle formed by wood or steel. Engineers prefer a girder bridge because it looks better, however it uses more materials. Arch bridges are another common type of bridge. Each span of an…

They consist of groups of triangular units to form a truss, acting primarily in tension and compression with the bridge. Truss bridges are one of the oldest bridge design since the Industrial Revolution. Trusses are rigid in structure with a high strength to weight ratio and possess the ability to transfer the load from a single point to a much wider area. Truss bridges can be made from wood, iron and steel or combination of those materials. There are numerous types of truss bridges associated…

There are two different truss types available during the construction of the bridge that includes truss type 1 and truss type 2. Both the designs are similar in nature but in this project the truss type 1 is chosen as the triangles help in making the bridge structure more stable. The second design of the bridge truss is beneficial for reducing the material usage and cost. By tilting the sides of the bridge in an inward manner will help in reducing wood usage that is required on the upper portion…

to provide an explanation of the assessments impact on teaching and learning. As part of the knowledge acquired during CTE 101, I was able to understand the importance of having both formative and summative assessments. Formative assessment constitutes of assessing students prior to the lesson begins so you can understand how much students know about the subject. On my bridge building and testing project, I ask students for examples of truss bridges in the area to find out if they know what a…
