Golden Gate Bridge
metal beams are place in the ground to support the golden gate bridge these beams are so strong so they can hold the support of the bridge and every thing else
One of the main reasons the golden gate bridge was used for was because before this bridge ever existed, the only way to cross the san francisco bay was by ferry, and once that got really crowded, the bridge was built, and helps a lot with the crossing of the bay. =]
The main cables which are securely anchored at each end and then drape over the towers. Smaller cables then hang from the main cables and suspend the roadway .
There are hundreds of "main" bridges all around the world. The best-known ones are: Ponte Vecchio bridge - a lovely old bridge in Florence, Italy containing small homes and businesses under and around it. Golden Gate bridge which was built between San Francisco and Sausalito to span the Golden Gate (Entrance to San Francisco bay) Millau Bridge - a super-modern suspension bridge in southern France Tower Bridge, a combination suspension and lift-bridge in London.
The main materials used to make the Golden Gate Bridge were 75,293,000 kg of steel; two main cables, each made of 27,572 strands of wire; 600,000 rivets in each of the towers; and concrete.The steel was made in New Jersey, Maryland and Pennsylvania and shipped through the Panama Canal.
There are many famous bridges in the world, some known for their beauty, some for their height or length or even age. Some of the most famous are The Golden Gate bridge in San Francisco, the Brooklyn Bridge in New York, the Akashi-Kaikyo in Japan and the Tower Bridge in London.
15500 kilograms were used in the bridge construction in the late 1800's. Twenty seven people died during the construction of the bridge as well. Very notable in history and it is free to go both ways.

One oreo is approximately 1.75 inches long...and the golden gate bridge is 4,200 feet long along the main span, so that works out to about 288,000 oreos. That works out to about 1,440,000 calories total, and if we are talking about Triple Double oreos (Three wafers with a section of vanilla and chocolate filling) that's about 2,880,000 CALORIES!!!
Well, a strait is a narrow (relatively) body of water that separates two land masses. And the call it "The Golden Gate" as San Francisco was the main port of departure & return to Alaska during the gold rush in the late 1800's.
The center of gravity of the Golden Gate Bridge is not a fixed point but rather depends on the distribution of weight throughout its structure, including the roadway, cables, and towers. Generally, the center of gravity is located near the middle of the bridge, closer to the main span, where the mass is more concentrated. Engineers consider this point during the design and construction phases to ensure stability and safety against forces like wind and seismic activity.
