Throughout the years submarine technology has advanced throughout the years from the original military submarine the turtle to the German u boats during WWII modern nuclear power submarines that we have today. These developments have required a lot of technological improvements. To make the u boats work the Germans need better battery and electrical motor technologies and the nuclear submarine obviously needed nuclear technology. Submarines have always been an innovative way to win the navel war.
During the American revolutionary war the British navy was a large part of the oppression of the American people. As a fresh nation we had little to no defense against the greatest navy in the world at the time. Ships in our harbor allowed the brats to limits plies and put large quantities of troops onto our shores very quickly. This was demonstrated after the Boston tea party when the British navy cut the city of Boston off from trade even though the ship that stayed docked was not a naval ship it is still a demonstration of the water sorority of the British people during the revolutionary time.
Some colonist got tired of this navel superiority and decided to do something about it. The turtle was born. The turtle was going to be the first submarine used for war purposes.
Design the turtle brought up ever before seen challenges. You could not use candle for light as the flame will use up air. Designers need to find way to move on all 3 axis. Lastly and most importantly it had to be airtight. There were unique solutions that to us now seem obvious. To solve the light issue a type of wood fungus called fox fire, this created its own issue in that if it fisted over it would stop working meaning that the mission would have to go forth in summer. To move on all the axis the torte had 3 impellers, one on top and 1 on either side. The craft also had a rudder. Moving up and down was achieved by having a tank in the bottom that could be flooded with water to sink and pump water out to rise meaning that you can change the amount of weight. Making a watercraft was basically done by building something that they already knew would hold water a barrel, essentially the turtle was a large barrel. Another design element was the lead keel that kept the craft upright.
In the second half of the eighteenth century, the British were faced with rebelling colonies. Finally realizing that they had to fight to keep their colonial possessions, the British sent troops to America. Once the battles began in America, the British were not impressed with the colonial military, but the weak militias soon proved to be effective. With foreign aid from France, American devotion, and the lack of British vigor, the Americans soon discovered the open doors of independence. In my opinion, the American advantages and the British disadvantages proved to be the downfall of the English in the American Revolution.
One of the main causes of the war was Great Britains's continued practice of impressment. The ocean was a common and affective way to transport good in order to trade with other nations. Every country has the right to use the ocean; but because Britain was causing America's rights to be restricted by capturing American ships and enslaving their seamen, it caused many problems between the two countries. Document 1 is a congressional report that describes Britain's violations of our right " to use the ocean, which is the common and scknowledged highway of nations, for the purposes of transporting, in their own vessels , the products of their own soil and the acquisitions of their own industry." The report calls Britain's impressment and seizure of ships is a
In the 1770’s the British army was well known for its monetary wealth and professional well trained militia. American colonists were slowly getting more and more fed up with the inequality and taxation under British rule so they took a stand. Americans known as Rebels or Patriots fought in the Revolutionary War to gain independence from Britain. Some colonists also known as loyalists, thought that the Patriots had no chance against the professional militia so they stayed loyal to the crown. Although improbable at the start of the American Revolution, the colonists were able to defeat the British army and formally gain independence because they had great leadership from George Washington, similar goals that created high morale, and aided from
This conclusion seemed to contradict every presumption about Great Britain’s imperial power. In all other conflicts, the British seemed to win decisively but the problem in the American Revolution lies with Britain underestimating the colonists. The British were blind to America’s symbolic presence as an end to an imperial structure. France and Spain aided the colonists in hopes of defeating the tyrannical empire. Britain underestimated George Washington and the Continental Army. Over time, the colonial militias trained in the European fashion and transformed into a challenging force. Ultimately, the most distinctive miscalculation of the British was the perseverance of the colonists and their fight for freedom. While Britain was fighting for control over yet another revenue source, America was fighting for independence and principle. The difference between the motivations was the predominant factor in deciding the
The origin of England's dependence on the colonies began during the French and Indian war, in the 1750s-1760s. In this war, the British were quite inexperienced; their European style of fighting did not work against the guerilla-warfare fighting style of the French. The British wore bright red coats, marched in long lines, often lugging cannons around with them, while the French hid behind trees and picked them off one by one. General Braddock relied on his force of ill-disciplined American militiamen, who used behind-the-tree methods of fighting in order to fight the Indians. After many years of fighting, the British finally came out victorious. Although England emerged from this war as one of the biggest empires in the world, it also possessed the biggest debt. They had poured much money and resources into these colonies in order to keep them as their own, and it was time for the colonies to give something back to the British for protecting them from the Indians. They finally realized what a precious gift the colonies were, and how useful they would be. In this war, the British realized that the colonies were their pawns in a global game of chess. At any time, the British felt that they had the right to impose taxes on the colonies, in order to make up for money that was lost in the French and Indian War to defend them. They had the view that because they had done so much to help the colonies, that the colonies had to repay them.
The turtle appears throughout giving the contextual symbolism of the struggles of the Joad family’s survival during the family’s travels to the west and new life. The turtle’s travels alongside the highway on the hot pavement and survives an attack by a driver who purposely swerved to hit the turtle, “And now a light truck approached, and as it came near, the driver saw the turtle and swerved to hit it. His front wheel struck the edge of the shell, flipped the turtle like a tiddly-wonk, spun it like a coin, and rolled it off the highway. The truck went back on its course along the right side”
The standard torpedo of the war suffered from early problems with its internal depth-keeping equipment, and its firing pistol, but these were solved after the Norwegian Campaign. In mid 1942 an improved version was introduced with an increased battery capacity. The increased battery capacity increased the range 50%.
This boat had quite an interesting design. It was made so that the hull was almost completely submerged, so much so that the sides peeked only a few inches above the water. The whole boat was completely made of iron unlike the CSS Virginia which had the wooden hull. The turret of the Monitor, was revolutionary as well. Although there was only two cannons, the turret was designed in such a way that it could rotate 360 degrees. This means that the turret can turn to shoot anywhere. There is no hiding from the Monitor, it has no blind spots. On top of having a full iron defence, being almost completely submerged, and a turret that has 360 vision, the USS Monitor was the first ship to have an underwater toilet (or restroom). This way, the soldiers were able to relieve themselves in the midst of battle to stay comfortable while the enemy had to hold their bladders and sometimes even soak their pants. The Monitor was indeed the peak of technology at the
The odontochelys preferred a similar habitat to the modern green sea turtle, in the shallow waters along different coastlines. Unlike the ancient green sea turtles, the younger modern day green sea turtles venture off into the deeper parts of the ocean and the adults stay near shore. Some of the original structural characteristics before any adaptation changes are: the row of sharp teeth on the top and bottom of the jaw and the stomach shell. Scientist suggests that these physical features were from the different types of prey that they needed to catch and because living on land exposed their stomachs, so they needed more protection from rocks and animals attacking them from underneath. Common behavior of todays green sea turtles are to only stay on land to bask in the sun and to lay eggs. The Odontochelys spent more than 50% of their time on land due to the lack of food in the shallows of the water and because most of the food sources were on land. One of the physiological adaptations of the Odontochelys, was adaption of the partial hard shell on top of it’s back. The pressures of nature forced this species to evolve into the different sea turtle species because of vulnerability of its back and because of the changes in availability of food. The Odontochelys had to spend more time in the water to either to escape from land predators or because they could no
Torpedoes are underwater devices that are self-propelled. They are highly explosive and very dangerous if put into the wrong hands. It has been used for destruction, war and many conflicts. They are still operating now. They were used all over the world in or above the water. They were mostly used in submarines. In this report, I’ll be explaining what torpedoes are, how they were used in world war 1, how they were used in the US navy and more.
Sea turtles are included as one of the many endangered animals in the world, yet not many people are aware of this. Therefore people should be informed about sea turtles characteristics, reproduction system and also learn about past incidents that has harmfully affected the sea turtles.
Amid unrestrained shouts and cheers, the first turtle crosses the finish line, and the winning "trainer" receives five dollars—along with a turtle necklace. What an uncharacteristic frenzy of emotion for the normally reserved folks of northern Minnesota!
“The Turtle” is a story by John Steinbeck, about the struggles of life and how to overcome them. The story starts by explaining how the desert is and the inhabitants of the desert. Steinbeck describes the desert as dry and bleak and many dead dry plants. The turtle first appears as a slow and feeble. Steinbeck describes the turtle as sluggish and distressed soul and he is trying to compare the turtle to a person who is trying to strain through life. The turtle is trying to climb the mountain and is having tribulations, but he is still pushing through even though he is moving little by little. He finally gets going well enough, then he gets to another struggle of having an ant climb into his shell and frightens him so bad that he climbs into
Turtles have existed for a very long time. They have existed for about 215 million years. Turtles have been alive a lot longer than mammals,crocodiles,birds,snakes and lizards. They can live up to about 200 years but most live until they are in their mid 70s. Turtles have a hard shell that protects them like a shield. This upper shell is called a carapace.The lower shell called a ‘plastron. The shell is attached to their spine and lower ribcage. It is different from other animal’s shells like the crab. The turtle’s shell is permanent, it cannot come off.
The submarine has advanced dramaticly due to war. The first major advancement in submarine technology is the invention of a gasoline and batery powered submarine by John P. Holland(Polmar 750). This ship was bought by the US Navy in 1900 and named the U.S.S Holland(Polmar 750). The U.S.S Holland was capable of speeds of 6 knots submerged(Polmar 750). The gasoline and battery powered combination allowed for submarines to run on gasoline while surfaced, and by battery power when submerged and combustion was no longer possable without wasting valuable oxogen within the submarine. The next leap in the technological development of the submarine was the periscope developed by Simon Lake in 1902(Polmar 750).
