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

CAREY FOSTER BRIDGE Introduction The Carey Foster bridge is an electrical circuit that can be used to measure very small resistances. It works on the same principle as Wheatstone’s bridge‚ which consists of four resistances‚ P‚ Q‚ R and S that are connected to each other as shown in the circuit diagram in Figure 1. In this circuit‚ G is a galvanometer‚ E is a lead accumulator‚ and K1 and K are the galvanometer key and the battery key respectively. If the values of the resistances are adjusted so

Bridge Project Questions 1- History of Bridges In the beginning bridges were very simple structures that were built from easily accessible natural resources- wooden logs‚ stone and dirt. Because of that‚ they had ability only to span very close distances‚ and their structural integrity was not high because mortar was not yet invented and rain slowly but constantly dissolved dirt fillings of the bridge. Revolution in the bridge construction came in Ancient Rome whose engineers found that

Truss bridges have many advantages that make it more useful for everyday use. The truss bridge is very economical to build and uses very few resources. It uses light materials and small loads of timber or whatever it is being made of. It is also one of the stronger bridges that can be built. The trusses on top of the bridge make it very strong because the triangle shape takes away much of the pressure and spreads the pressure to the triangles and takes it away from the road part of the bridge.

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
