Pratt Truss Bridge

Pratt Truss Bridge The purpose of this experiment is to study several bridges and build a bridge similar to the one that gave the students the uppermost muse. The students had to research facts about Truss Bridges, including its beginnings during the late 1700’s. Early Truss Bridge builders were first to spread its name throughout the United States, but the name of Truss Bridges soon cultivated across the world. There were numerous reasons as to why the design of Truss Bridges grew so broad. Firstly, the Revolutionary War destroyed the limited transportation the United States had left. The innovative and enhanced United States needed a more advanced form of transportation. For the reason that iron was not freely available, the idea of using
Each new builder has taken previous builder designs and added different components to them. A cou-ple well known Truss Bridges around the World are the Bagga Bridge, the Kuronosetto Bridge, and the Collins Bridge. These bridges were stimulated by famous enterprises such as the Pratt, Warren, and Parker bridges. To begin, The Pratt Bridge can be described by a basic layout con-sisting of compressed diagonal and vertical rods. In 1844, engineer Thomas Pratt and his father offered a standard and inexpensive design reposed with numerous plates, bars, rods, and beams. This design outclassed many other ideas and became an effective element during the final era of the 19th and 20th century. On the other hand, another impeccable design is the unique Warren Truss, which is classified by its consistent and sturdy material. Using thick and prominent diago-nals ability to act in both a straining and confining manner. Furthermore, the Parker Truss, which is named after the engineer, C.H. Parker who was a major part in the contribution to the devel-opment of this design in the 19th century. This Truss is extremely similar to the Pratt Truss, its only difference is that it contains a polygonal top chord. A polygonal top chords saves materials and the center span has the greatest depth where it is most needed (Types of Bridges, June
Each type of design is although, unique in its own way, fulfills the desired goal that the Truss Brides are made for. The purpose of this experiment is to research various bridges and build a similar one that gave the students the highest inspiration. For one case in particular, the bridge design was in-spired by the Pratt Bridge and almost every height, width, and length met the requirements ex-cept for the length on the bottom part of the bridge, it exceeded the maximum height that was asked. Moreover the bridge held a total of 20 pounds before one of the top sticks snapped. Alt-hough it performed a decent job, the bridge could have held more weight if there were more di-agonals to provide more support so the bridge wouldn't break. Furthermore, this bridge fulfilled its goal and held a large amount of weight for such a small bridge. These bridges are also very significant for this planet because it is very resourceful and effective, as well as
