The Truss Bridge Project

Improved Essays
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. Although with these strict regulations, there are a few areas left questionable; such as: how does this method of testing differ to the other method from past years and how do we evenly distribute the work amongst the four members of this group? Each member brainstormed and designed 6 truss bridge models, determined their top 2, and reasoned why their particular design was best. Ultimately, Darrell, Pasesa, and Logan’s suggestions were eliminated, and concluded that our best approach would be within Jarren’s design.

Basically we placed our bridge between an east and west abutment, which then we inserted a testing block and a testing rod. We secured the testing block directly at the middle and fully rotated the rod until Mrs.Tokuhama’s clearance. From then on, we rotated a wheel, which was the Force LBF , and it simply acted as a load. As we continued to turn the wheel right, the more force or more weight would be applied onto the bridge. We began hearing cracking and seeing an arch form at the top of the superstructure at 45 Force LBF. Our bridge reached a certain point to where there was too much stress onto the bridge, that the Force LBF retracted back to 46 pound-force, then we only we went up 4 more pound-force until we called it

    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 means…

    Introduction: 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…
