Truss bridge

Intro; A bridge is a structure that is built over a river, road, or railway to allow people and vehicles to cross from one side to the other. (CambridgeDictionaryOnline.com) Bridges come in many different shapes sizes and designs. However there multiple different categories of bridges ranging from 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 Compression and tension Compression being a compressive force that acts to compress or shorten the thing it is acting on. Tension…

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 means of hinged joints or rollers, it’s described as…

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. Teachers will be…

Bridge Design: 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.

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 this bridge…

With the assignment of this Truss Bridge project, our primary objective was to design a sturdy bridge, with the durability to withstand the heaviest load over an allotted time span using limited materials, yet cost efficient. To participate and qualify in this project, we must comprehend the guidelines and statutes to avoid disqualification. The criteria and constraints will contain specific and precise measurements of a length, width, and height pertaining to either the roadbed or bridge.…

to a truss only at the joints, forces are transmitted only in the direction of each of its members. That is, the members experience tension or compression forces, but not bending forces. Trusses have a high strength to weight ratio and consequently are used in many structures, from bridges, to roof supports, to space stations.The Pros of a Truss Bridge 1. They might be light, but they are also strong. Truss bridges utilize the materials that are needed to create them very effectively. This…

The bridge lab project was based on the given scenario in which a reliable bridge needed to be constructed over a river in order to alleviate traffic. The objective was to design a bridge to relieve traffic flow that was also safe, cost effective, and aesthetically pleasing. The constraints for this project included the budget and minimum height and width requirements. The max budget to purchase wood was $200, the minimum height at all points of the bridge was 3 inches, the minimum width of the…

paragraph 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…
