Simple Machines   Ã‚  Ã‚  Ã‚  Ã‚  A windmill is a machine that uses the wind to turn a wheel of adjustable vanes, slats or sails. As the wheel turns, it turns a shaft, wheels, and gears that power machinery. It is more properly called a â€Å"wind pump,† but most people call it a â€Å"windmill.† Windmills have been used for hundred of years to power machinery used to grind grain such as wheat and corn. Today we also have windmills, called â€Å"wind turbines,† that generate electricity.  Ã‚  Ã‚  Ã‚  Ã‚   All machines are a combination of several simple machines or modifications of one. A simple machine is one that is moved by just one force. The six types of simple machines are the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw. A lever is a long plank, beam or bar that is used to move heavy loads. Examples of a lever are seesaws, scissors, broom, tweezers, and ice-tongs. A wheel is a cylindrical object that rotates about axis of the cylinder. Wheels are on cars and trains. Some wheels turn other wheels, like geared wheels on a bicycle or a clock. Some wheels turn together like the doorknobs, or the knobs on a televisions. A pulley is a grooved wheel. A rope is fitted into the grove and turns the wheel when pulled. An inclined plane is a very simple machine. It has a sloping surface that makes it easier to pull, push, or roll heavy objects. Examples are wheelchair ramps or a stairway. The screw is an inclined plane wound at its edge on a cylinder or cone. Examples of a screw includes faucets,   Ã‚  Ã‚  Ã‚  Ã‚   Saizan 2 screw-in bulbs, and screw-on bottle tops. The wedge is essentially an inclined plane such as knives, blades, nails, needles, pins, wood and axes.

Whip it

Bliss is curious about joining the roller derby team while in Austin, TX for the derby event, but her friend, Pass, is doubtful about her actually trying out for the team. Pass brings up several factors about why Bliss wouldn't try out Including her not having the guts to try out, her not being as tough as the other roller derby girls, and the fact that her mother would disapprove of It. Plus, although Pass TLD exactly mention It, Bliss wasn't the appropriate age to Join the team. She had to be 21 to join the team and she was only 17.I felt like Pass was bringing up all of Bliss' flaws not to put her down, but to make her want to prove her wrong and go for it. As the movie explores the relationship between Bliss and her mother, I feel like nobody's really happy with each other's decisions. Bliss wants to find direction in her life and follow her heart's desire while her mother aspires for her to be a beauty queen like she once was as a teen. Even though they both don't really see eye to eye about their differences, Bliss goes along with her mom's wishes o please her, so in a sense, I suppose her mother is happier in the situation.The things that they have In common are their love for each other even if it's not shown too often throughout the film, and their passion for what they love to do In life: Bliss' roller derby racing and her mother's beauty pageants. How Bliss and her mother view each other Is pretty similar. Her mother sees beauty and Intelligence wealth Bliss, and feels that both can surface by competing in the beauty pageants. Bliss also sees the beauty in her mother, although her mom feels like this has faded away wrought the years.Bliss' mother sees herself as a former beauty queen who has aged and often reflects on the days when she was younger. Bliss sees herself as a girl who just isn't the beauty pageant type, but has other special qualities about her that may not set well with her mother. I view Bliss as a girl who knows that there's courage a nd strength within her and strives to bring them out. From the very beginning of the movie, I felt that she knew there was a certain path she was supposed to be following but was uncertain of what It was.From her dyeing her hair blue and becoming Interested In roller derby at the head shop that day, I think she knew that she was different and was destined to be a free spirit. I view her mother as someone who honestly just wants the best for her daughters, but can be too overprotective of them and unreceptive to what they truly want out of life. She's definitely strong and stands firm in her beliefs, it even showed in her facial expressions that she was a woman of dignity. I got the feeling that she knew how tough life can be and she didn't want her daughters going through any mind of pain if she could help it.I could see her reasons for wanting to protect Bliss from the world, but I feel that she shouldn't have pushed her beauty pageant dreams onto Bliss. With Bliss' participation i n roller derby racing, I feel like it liberated her and helped her confront her mother about what she really wants to do with her life. I also feel that she gave her father a sense of pride which we can see by him putting her Jersey number In the yard at the end of the movie. We could see how her decision affected her family as a whole.What roller derby almost costs her was her almost consumed by her newfound life of roller derby, and she had to really face the good and bad that came with it. Vive experienced this as well with some of my leisurely choices. Vive learned that no matter what you're passionate about, there's always an upside and downside waiting for you Just down the road. The key to not letting the downsides knock you off your axis is to stay focused and to never let friends and family fall to the wayside while pursuing that passion.

Impressment and the Chesapeake-Leopard Affair

The impressment of United States seamen from American ships by the British Royal Naval created serious friction between the United States and Britain. This tension was heightened by the Chesapeake-Leopard Affair in 1807 and was a major cause of the  War of 1812.   Impressment and the British Royal Navy Impressment denotes the forceful taking of men and placing them into a navy. It was done without notice and was commonly used by the British Royal Navy in order to crew their warships. The Royal Navy normally used it during wartime when not only British merchant sailors were â€Å"impressed† but also sailors from other countries. This practice was also known as â€Å"the press† or â€Å"press gang† and it was first used by the Royal Navy in 1664 at the onset of the Anglo-Dutch wars. Although most British citizens strongly disapproved of impressment as being unconstitutional because they were not subject to conscription for other military branches, the British courts upheld this practice. This was mainly due to the fact that naval power was vital to Britain maintaining its’ existence.   The HMS Leopard and the USS Chesapeake In June 1807, the British HMS Leopard opened fire on USS Chesapeake which was forced to surrender. British sailors then removed four men from the Chesapeake who had deserted from the British Navy. Only one of the four was a British citizen, with the three others being Americans who had been impressed into British naval service. Their impressment caused widespread public outrage in the U.S. At the time, the British, as well as most of Europe, were engaged in fighting the French in what is known as the Napoleonic Wars, with the battles starting in 1803. In 1806, a hurricane damaged two French warships, the Cybelle  and  Patriot, which made their way into Chesapeake Bay for necessary repairs so that they could make the return trip to France.   In 1807, the British Royal Navy had a number of ships, including the Melampus and the  Halifax, which were conducting a blockade off the United States coast in order to capture Cybelle and Patriot if they became seaworthy and left Chesapeake Bay, as well as prevent the French from obtaining much needed supplies from the U.S. Several men from the British ships deserted and sought the protection of the U.S. government. They had deserted near Portsmouth, Virginia, and made their way into the city where they were seen by naval officers from their respective ships. The British request that these deserters be handed over was completely ignored by local American authorities and enraged Vice Admiral George Cranfield Berkeley, the Commander of the British North American Station at Halifax, Nova Scotia. Four of the deserters, one of which was a British citizen - Jenkins Ratford – with the three others – William Ware, Daniel Martin, and John Strachan – being Americans who had been impressed into British naval service, enlisted in the U.S. Navy. They were stationed on the USS Chesapeake which just happened to be moored in Portsmouth and was about to embark on a trip to the Mediterranean Sea. Upon learning that Ratford had been bragging about his escape from the British custody, Vice Admiral Berkeley had issued an order that if a ship of the Royal Navy should find the  Chesapeake at sea, it was that ship’s duty to stop the Chesapeake and capture the deserters. The British were very intent on making an example of these deserters. On June 22, 1807, the Chesapeake left its’ port Chesapeake Bay and as it sailed past Cape Henry, Captain Salisbury Humphreys of the HMS Leopard sent a small boat to the  Chesapeake  and gave Commodore James Barron a copy of Admiral Berkeley orders that the deserters were to be arrested.   After Barron refused, the Leopard fired almost point blank seven cannon balls into the unprepared Chesapeake which was outgunned and therefore was forced to almost immediately surrender. The Chesapeake suffered several causalities during this very brief skirmish and in addition, the British took custody of the four deserters. The four deserters were taken to Halifax to be tried. The Chesapeake had suffered a fair amount of damage, but was able to return to Norfolk where the news of what had taken place quickly spread.   Once this news was made known throughout the United States which had very recently rid itself of British rule these further transgressions by the British was met with complete and total disdain.   American Reaction The American public was furious and demanded that the United States declare war against the British.   President Thomas Jefferson proclaimed that â€Å"Never since the Battle of Lexington have I seen this country in such a state of exasperation as at present, and even that did not produce such unanimity.† Although they were normally politically polar opposites, the Republican  and  Federalist parties were both aligned and it appeared that U.S. and Britain would soon be at war. However, President Jeffersons hands were tied militarily because the American army was small in number due to the Republicans desire to reduce government spending. In addition, the U.S. Navy was also quite small and most ships were deployed in the Mediterranean attempting to stop the Barbary pirates from destroying trade routes. President Jefferson was intentionally slow in taking action against the British knowing that the calls from war would subside – which they did. Instead of war, President Jefferson called for economic pressure against Britain with the result being the  Embargo Act. The Embargo Act proved to be highly unpopular with American merchant who had benefited for nearly a decade from the conflict between the British and the French, collecting large profits by conducting trade with both sides while maintaining neutrality. Aftermath In the end, the embargoes and economic did not work with the American merchants losing their shipping rights because Great Britain refused to make any concessions to the U.S. It seemed evident that only war would restore the United States autonomy in shipping. On June 18, 1812, the United States declared war against Great Britain with a major reason being trade restrictions which had been imposed by the British. Commodore Barron was found guilty of â€Å"neglecting on the probability of an engagement, to clear his ship for action,† and was suspended from the U.S. Navy for five years without pay. On August 31, 1807, Ratford was convicted by court-martial for mutiny and desertion among other charges. He was sentenced to death the Royal Navy hanged him from a sail mast of the HMS  Halifax – the ship that he had escaped from looking for his freedom. While there is truly no way of knowing just how many American sailors were impressed into the Royal Navy, it is estimated that over one thousand men were impressed per year into the British service.
