What what was the problem with the iron bridges?
The problem with iron bridges was that the material was not as reliable as carbon steel, so it was replaced starting in the late 1800s and was completely unavailable for bridge building by the early 1900s. Bridges in the late 1700s were made of cast iron, but, by the early 1800s, cast iron gave way to wrought iron.
What are bridges normally made from?
iron and steel
What is the suspension bridge made out of?
Truss Bridges=Trusses have been used extensively in bridges since the early 19th Century. Early truss bridges were made of wood.==in additon the classic American covered bridges are all trusses, though the wooden truss members are covered by walls and a roof, for protection from the elements. Later truss bridges were made of cast iron and wrought iron. Most modern trusses are made of structural steel.=
How and why is iron important?
Iron is important because it makes steel for steel is made of 98% iron. It is also used in buildings, bridges and other objects that need to be strong.
The Eiffel Tower was made using what type of construction?
Similer to what we use for the world trade center and our bridges
What are steel bridges made of?
steel bridges are made out of steel OBVIOUSLY !!!
Do all iron objects rust at the same rate?
Nope,believe it or not they actually make iron beams/steel for bridges that is made to form a protective coating of rust to prevent the iron/steel from corroding/oxidizing away over time.then they have a primer paint that is made to etch into the rust coating bonding to it.this is all i know.so it depends on if you mean pure iron/steel or alloys.or the treatment of the iron when it is made
In the Iron Man movie is the suit cgi?

How did steel bridge construction evolve?
bridges made of cast iron often shattered and collapsed under the tremendous weight of the steam locomotives, so bridge builders turned to wrought iron, which has greater elasticity under stress.
What are the bridges made of?
Usually bridges are made of steel and/or concrete. Concrete bridges have steel reinforcement embedded within the concrete, because concrete is weak in tension. Steel is strong in tension and compression, which makes suspension bridges practical. Every nut and bolt, steel member size and thickness, and every other component on a bridge has been located and sized by using mathematics to calculate all the forces applied to each component of the bridge, which must be resisted by the materials used.
Why bridges are made?
bridges are made to cross the rivers by train.
