Bridges and Tunnels

Harold Godwinson defeated Harald hardrada mainly because many of hardrada's men didn't have their armour as they were not expecting godwinsons arrival. also the vikings guarding the bridge were killed so hardradas men had no warning thus they didn't see them coming.

the mayan civilization fell do to over population and disease from the spanish.......do to diseases such as small pox ....etc

it started in 400BC and began to collapse in 900AD

No one exactly knows what caused this massive, successful civilization to come to an end. There will never be a 100 % known answer. There are many theories as to what happened. One of them is that they were living in a volcanic region where one erupted. If this were to happen, the lands would be blanketed with ash and this would have forced the Mayans to move their entire civilization. Some say it was because of a strong unknown upheaval. Others say that the Mayans went against their Gods and forced themselves to starve and burn their temples. One other is that tehre was a dramatic temperature change where the farmers could not adapt and this caused them all to starve as the crops would not grow. Hope this helps :)

During a glaciation, water evaporated from the oceans falls on the land in higher latitudes as snow. If the snow doesn't melt during successive cold summers it builds up and turns to ice. Repeated evaporation and snowfall causes the oceans to lose water over many years, this causes the level of the oceans to drop, revealing more land above sea level. What was previously a shallow sea becomes dry land, hence a "land bridge".

Advantages:

(1) The market gives producers an incentive to produce goods that consumers want.

(2) The market provides an incentive to acquire useful skills.

(3) The price system encourages producers and consumers to conserve scarce resources.

(4) Competition pushes businesses to be efficient: keeping costs down and production high.

(5) The market system involves a high degree of economic freedom.

Disadvantages:

(1) A private market economy may be quite unstable (unemployment, inflation, growth)

(2) Business may simply satisfy the wants they have created through advertising.

(3) Prices may give false or inadequate signals to producers and consumers (externalities, like pollution).

(4) Markets just do not work in some areas (public goods, such as national defense).

(5) Monopolistic industries may restrict output and drive up prices.

(6) Market economies tend to produce a skewed distribution of income (large gap between the rich and the poor).

(Since this is world wide please note:Americans use the term Tories where English use Loyalist to describe those loyal to the crown. Likewise they use Whigs where English use Patriots.) Lord Dunmore commanded the British Army. William Wofford commanded the Whig Army. On December 9, 1775, Lord Dunmore's army found the Whig army encamped behind large earthworks near The Great Dismal Swamp in Virginia at Great Bridge.

The British Army would climb the earthworks into a volley of gunfire. Then it would retreat. The British officers believed that eventually the Whigs would run out of ammunition like they did at Bunker Hill. Then they could overpower the Whig army with fixed bayonets. Before the Whigs ran out of Ammunition, a large Whig militia force from North Carolina joined the battle. The British were outnumbered and abandoned the battlefield. They fled to the Tory town of Norfolk, Virginia.

Harold Godwinson (King Harold II) had killed the Norwegian leader called Harald Hardrada in 1066. Harold II's traitorous brother Tostig was also killed fighting with the Norwegians. Stamford Bridge is in Yorkshire, England.

Advantage: It is strong. Also the cables won't break under extreme temperatures.

Disadvantages: Wind is a big factor. It can rock the bridge side to side, causing the cables to become lose.

The first cast iron bridge is located, fittingly, at Ironbridge in England. It spans the river Severn, and was built in 1779. It is still standing.

The English (who had been camped waiting for the Normans [or French] to invade) raced up to fight the Viking force that had invaded England in the north. The English won, and then had to leg it down the the battle of Hastings as the Normans had invaded whilst the English were fighting up at Stamford Bridge. The Normans then beat the English at the battle of Hastings (the one made famous for the arrow to the eye of King Harrold - although it was probably horsemen that killed him)

Monday 25th September 1066

The battle of Stamford Bridge was between Harald Hardraada, a tough viking, and the new King Harold Godwinson. Before Harald Hardraada fought Harold Godwinson, he fought two English Earls: Edwin and Morcar, I believe, in York.

To the point, in the battle of Stamford Bridge the English fought in tight ranks while the vikings where split up. Harold Godwinnson used a formation called the ramming formation to break to the vikings. after that an archer shot Hardradas throat and most of the vikings fled. the rest swapped sides.

After the battle of Stamford Bridge, only about 200 soldiers/ships went back, despite the thousands he brought over. Harald Hardraada lost whilst Harold Godwinson claimed victory but later had to go and fight William of Normandy and his Norman army in the battle of Hastings

Both the Battle of Stamford Bridge and The Battle of Hastings were fought in England. The Battle of Hastings is said to be the most famous English battle ever.

It is believed that 12 workers in total died during the construction of the George Washington bridge. Many people have committed suicide by jumping from this bridge.

A truss bridges are designed using materials that are connected in a manner to be stressed under tension and/or compression. I truss system can be designed to be as long as necessary. Columns are also used in truss desins to reduce deflections.

A cable suspension bridge is a kind of bridge hung from cables.

The Severn Bridge is located close to the former Aust Ferry. The bridge is a suspension bridge of conventional design, with the deck supported by two main cables slung between two steel towers. In 1966 the cables supporting the bridge deck were spun from 18,000 miles (29,000 km) of wire[5]. The bridge is 5,240 ft (1,600 m) long, consisting of a 3,240 ft (988 m) central span between the towers and the two 1,000 ft (305 m) side spans. The towers rise to 445 ft (136 m) above mean high water and are of hollow box construction. The deck is an orthotropic steel box girder of aerofoil shape with cantilevered cycle tracks and footway supported from the box
