What is the strongest balsa wood bridge?
I built this bridge for the 2005 Fernbank Science Center bridge design event. This is the strongest bridge I have ever built. The bridge spanned 16 inches, weighed 37 grams, and held 346 pounds.
How do you make a wooden bridge stronger?
You can mix wood glue with water to cut down on weight. Doing this also helps the glue to seep into the wood, creating a stronger joint.
What type of bridge can hold the most weight?
The arch bridge can hold the most weight of the three, the deck truss bridge can hold an average amount of weight, and the beam bridge could hold the least amount of weight.
What is the strongest bridge in the world?
Firth of Forth Bridge Notably one of the strongest bridges in the world, the Firth of Forth had to be strong since its primary function was for railroad loading. Today, this Highlands workhorse still supports between 150 and 180 trains each day taking people from Glasgow to Edinburgh and all stops in-between.
What type of Toothpick bridge is the strongest?
A truss bridge is a befitting example of this type. A truss is a structure made of triangles which make it very strong to withstand heavy weights.
What makes a good bridge design?
The prototypical bridge is quite simple—two supports holding up a beam—yet the engineering problems that must be overcome even in this simple form are inherent in every bridge: the supports must be strong enough to hold the structure up, and the span between supports must be strong enough to carry the loads.
What is the weakest bridge?
We did further research after our experiment and learned that beam bridges are actually the weakest of all bridges and suspension bridges are the strongest.
What is the most expensive type of bridge to build?
Suspension Bridge Pleasing to look at, light, and strong, suspension bridges can span distances from 2,000 to 7,000 feet—far longer than any other kind of bridge. They also tend to be the most expensive to build.
What is the most stable type of bridge?
A truss bridge is the strongest kind of bridge. They flex less than other kinds of bridges and provide greater stability even in extreme weather or traffic. Truss bridges have a basic design that couples repeated triangular conglomeration so as to create a matrix of support structures.
What is the most structurally sound bridge design?
Truss bridges are extremely effective because they have a high strength to weight ratio. In this experiment we have tested which type of truss bridge is the strongest, yet uses the least amount of material. Two of the most used truss bridges are of the Pratt and Howe design.
What is the most common truss bridge?
Originally designed in 1844 by railway engineers Thomas and Caleb Pratt, the Pratt truss bridge is one of the most common bridge designs.
