What factors affect the bending of bridges? Abstract: This experiment was designed and conducted to find out how different factors affect the amount of bending of the beam. The two variables that were tested were the amounts of weight and the position of the weight on the plank. Aim: To find out how weight and different placements of the weight affect the bending of the beam. Hypothesis: It is predicted that the wood will bend more if there is more weight on it. When the weight is positioned

Bridge Structures and The Use of Geometry in Their Design What is a bridge? A bridge is a structure providing continuous passage over a body of water‚ roadway‚ or valley. Every bridge looks different from the another. Their bridge structure is different. There are nine types of main bridges. Bridge engineers use a lot of geometry to help them design the different bridges. Without geometry‚ the bridges would not be safe. Bridges have been around for a long time. The earliest bridges

Bridge Failure Studies and Safety Engineering 2.1 HISTORY OF DISASTERS AND SAFETY MANAGEMENT 2.1.1 Unexpected Material Deterioration and Failure Engineering is usually about avoiding failures and investigating why failures occur and ways to fix the problem. There is a need to understand the conditions giving rise to past failures and ways to avoid such failures so that loss of life can be minimized. Historical events and selected case stud-ies demonstrate the causes of

For instance‚ the Baltimore‚ Pennsylvania‚ and the Parker are all based off the Pratt. Pratt Truss How the forces are spread out Here are two diagrams showing how the forces are spread out when the Pratt Truss is under a load. The first shows the load being applied across the entire top of the bridge. The second shows a localized load in the center of the bridge. In both

2/4/2013 Bridge improvements Building a bridge was trial and error. This is not something you can do over night. When building the bridge I have to focus on the structure‚ details and actually putting it together right. The structure of my frame I made with the thicker wood‚ but it should have been placed different. Looking at the data from testing other bridges‚ the bridges who double bonded their wood at the bottom last a lot longer that the one piece of wood. My bridge failed when one

Overview Padma Bridge is one of major outstanding infrastructure required for balanced economic development of Bangladesh. It is anticipated that the gross domestic product of the would increase by 2 percent once the bridge was constructed. The bridge‚ which would connect the southwest region with the rest of the country‚ could be used for the trans-Asian route; the minister said adding "The Bridge will help gear up industrialisation in the region too."Environmental impact of the bridge would be assessed

Bonus Bridge Paper Transportation is key in today’s society. It’s all about getting from one place to another in the quickest way possible. The inconvenience of going around something or going directly through can be tiring and can take up a lot of time. That’s where bridges come in. A bridge is a structure carrying a road‚ path or railroad across bodies of water‚ other roads or any object that may be an obstacle. Although there are many different types of bridges‚ they all deal with compressible

The trestle bridge is built with lateral and angled bracing‚ and horizontal and vertical reinforcements; to ensure the bridge can bear maximum weight. The base of the bridge is simply constructed with lateral bracing which is connected by horizontal panels that are connected to a horizontal‚ upright‚ panel on either side. Although‚ engineers rarely place lateral bracing on the base‚ it provides for extra stability. Moreover‚ the base also has upright and angled Popsicle sticks connected to the lateral
