...PHY II ESSAY REPORT Wheatstone Bridge and Resistance The 19th century was as very good era of discovery in electrical knowledge, and technology that laid the foundation for what we see today in our society. Scientist like Luigi Galvani for his work with frogs led to his discovery in 1781 of galvanic or voltaic electricity. Galvani found he could make the muscles of a dead frog twitch when he touched them with different metals or the current from a nearby static electric generator. Alessondra Volta for creating the first battery laid the foundation for many other great discoveries in this field. Some other great concepts that came later in 19th century was Ohms law, Electromagnetism, Faraday law, and many more. A discovery of great significant was done by Samule Hunter Chrisite in 1833 and improved by Charles Wheatstone in 1843. This discovery used a device know as a wheat stone bridge, which gives a precise method to measure resistance against a known standard. In the Wheatstone a comparative device measures two additional relative resistance from two separate resistors. The relative resistance equals the lengths of a divided wire wound in a coil of ten-turns within a potentiometer, a device allowing the manipulation of this resistant ratio. The goal of the this lab is to accurately use the methods created by the inventors by simulating their method in discovering this new phenomenon . In the lab we measured the electrical resistance using Wheatstone bridge...

...Bridge to Teribithia is a book about a boy named Jess Aarons. He changes when he becomes friends with Leslie, the class outsider. Both kids create an imaginary world in the forest called Teribithia where there are magical creatures. Jess and Leslie rule as king and queen in Teribithia. When Leslie dies from an accident in Teribithia, Jess must use what she has taught him in order to recover from the horrifying loss of his friend. Leslie is talkative, openly social more open minded about the world around her and while Jess is poor, she's rich. At the beginning of the movie and book, she's the new girl who dresses different, talks different, and doesn't play by the same social rules as the other kids do. She is highly intelligent and imaginative; it is her idea to build a fantasyland named Teribithia across the creek. She is also athletic because she beated Jess in a race that he had trained for all summer. Even though Jess is a boy and Leslie is a girl they both share some things in common. Jess and Leslie both share a love for running. Jess is a good runner who aspires to be the fastest runner in his class. Leslie is a great runner who manages to beat even all the boys the first time she races them. Both Jess and Leslie have very creative personalities. Jess is an artist, and although his work is generally...

...Hello, today I will be talking about different types of bridges! There are 6 general types of bridges and we will talk about all of the types of bridges there are. Now, we believe that there are five main types of bridges to begin with. These types are beam, truss, arch, cantilever, and suspension. First, we will talk about beam bridges. Now, beam bridges are very basic bridge constructions that have pieces on each end of the bridge. These types of frequently use leg supports to distribute the load equally throughout the whole bridge. Different types of beam bridges are girder bridges and box girder bridges. Beam bridges work a lot like a log overlapping two sides of a ravine. Famous beam bridge, the 7 Mile Bridge in the Florida keys. Next,...

...The film about An Occurrence of Owl Creek Bridge was a film with different ironies. The director of the film was Robert Enrico. The film was about a man that was being hung on the bridge on top of the creek. He was surrounded by an army, just in case he wanted to escape. Throughout the film he had an illusion about him escaping and running to his family. Obviously it was just an illusion because at the end of the film he was hung and died. One of main theme is death because we can die in seconds, minutes, or hours. In the little time of Peyton’s life he had a dream, and in a little bit of seconds he was able to dream about him escaping. 1.) The main character was Peyton Farquhar. 2.) The settings was when he was about to be hung....

...The collapse of the Tacoma Narrow Bridge was a disaster back in the 1940 that is still known to many today. Many physicists have attributed the collapse of the bridge to forced resonance of the mechanical oscillator – where the wind has provided a source of periodic frequency that has tallied the natural frequency of the bridge. (Scanlan, 1990) In fact, there were multiple arguments that have led physicists to conclude that the tragedy was a result of resonance. Although this reasoning has existed for the past few decades and was agreed by physicists, many engineers have found out that such argument was mischaracterised. One of the reasons was that the frequency of the bridge (under 42 mph wind) was 1Hz, which was not close to the actual frequency (0.2Hz) observed during the tragedy. The Van Karman Vortex Street would not be able to result in resonant behaviour on the day of the collapse. There are many more arguments that were supported by different physicists and in this paper, these explanations will be highlighted and evaluated. Some physicists have come up with an argument that attributed such tragedy to...

...I would like to take part in the Bridges summer program because I’m a dedicated, determined and ambitious student that wants to get a head start in college. I have taken on the task of graduating a year early so I can go above and beyond my education in the field I would like to pursue. The Bridges summer program helps me start on a higher level than my peers who might also be going into Computer Science. I have also heard about the great and beneficial opportunities that I could have if I go to Valencia before starting off at the University of Central Florida. It’s a great opportunity to use my summers for something other than sitting behind the computer playing games or sleeping… although those things sound great and like a fun way to spend...

...Construction of the Bridge The construction of the New Tacoma Bridge, which was supposed to replace the old Tacoma Bridge of 1940 which had collapsed took a very long time. The replacement of the old Bridge was delayed for almost a year due to demand of steel which was created by the World War II and also trouble in arranging insurance which would be used for the new bridge. On 30th April 1947 Governor Mon Wallgren announced that the insurance of the bridge had finally been made and arranged. On August 1947 Washington agreed with the request to build the bridge with the construction price having shifted from .8.5 million to 11.2million. On 15th October 1947, the state established bids for construction of the New Bridge, with John A. Roebling’s sons company which was from San Francisco bidding 31.1 million in present terms to be used to constructing the suspension Cable system and...

...Ambrose Bierce was an author who had a way of writing a story that was deeply felt by its reader. In “An Occurrence at Owl Creek Bridge” the main character, Peyton Farquhar, is being hanged by war hardened soldiers. Farquhar has a vision just mere seconds before he dies, a vision in which the soldiers fire continuous rounds from cannon and rifle at him. “Chickamauga” is about a boy of just six years old who is a deaf mute. He wanders through the woods with a wooden sword in hand, playing soldier. He falls asleep and wakes to the sight of crippled, dying soldiers retreating from battle. In “An Occurrence at Owl Creek Bridge” and “Chickamauga” Ambrose Bierce makes the reader understand the utter darkness of death by using imagery, foreshadowing,...

...Introduction The Bridge River archaeological project has been ongoing since 2003. The Bridge River archaeological site is located in the Mid Fraser Valley in British Columbia, Canada. The site is just a few kilometers from the town of Lillooet in British Columbia. There are a total of ten Bands in the St’át’imc First Nation. They are the Xwisten, Ts’kw’aylaxw, Xaxli’p, Tsal’alh, T’it’q’et, Sekw’el’was, N’quatqua, Samahquam, Skatin, and Xa’xtsa. These bands have been in the area for hundreds of years, with their ancestors living in the vicinity for thousands of years. The Bridge River Band or the Xwisten First Nation are the decendents of the people that occupied the Bridge River site. They reside just below the terrace that the Bridge...

...I am Wiley Hayes, and I serve a double role with Beyond the Bridges Ministry. I work as the program’s administrative assistant, managing day-to-day office and program responsibilities. I also mentor new participants, encouraging them to face the challenges of re-entry and providing advice and support as they solve practical problems, such as housing and job search. It is gratifying for me to serve in this way, because the assistance BTB offers can make the difference between ex-offenders getting their lives back on track to re-enter the community or slipping back into old behaviors that return them to prison. I have a special reason for knowing this. I have spent a total of 20 years of my life behind bars. My last conviction sent me to prison for 15 years. I know personally what it is like to come out of prison to face re-entry into the community without housing, without a job, and without a supportive group of caring people to encourage and advise me. Release from prison can present challenges so overwhelming that they lead the unprepared ex-offender back to prison. The key that helped me to survive this demanding time I never would have suspected earlier in my...

...Occurrence at Owl Creek Bridge. The way Bierce conveys suspense leaves the readers on edge, grabbing their attention. With Peyton Farquhar being the protagonist, readers know everything about him; who he is, what he does, and what he thinks and feels. Parts one and two of the short story the narrator gives an account of what Peyton Farquhar was accused of and/or guilty of but also why he was at the bridge, part three is told in flashback style, which is one of many methods used to contribute to the suspense of the short story. Bierce’s use of flashbacks, imagery, and the chronological order of the story all contribute to a suspenseful effect. Flashbacks throughout the story take part in a major role of suspense by making the story seem longer than it actually is. In part two of the story Peyton and his wife are visited by a soldier who informs them ”The Yanks are repairing the railroads…any civilian caught interfering with the railroad, its bridges, tunnels or trains will be summarily hanged”(532). With the scout being a soldier from the North and Peyton being a plantation owner from the South adds suspense due to the different of opinions of what is right and wrong. Normal chronological order is disrupted through this story with news of the hanging placed at the end rather than the...

...With my head down, I had just walked back to my desk, ready to accept failure. Being one of the last ones to finish the assignments, I had thought for sure I wouldn’t have gotten a good grade on it. As the teacher was reading through the essays, she called me up to her desk. She hadn’t called up anyone else. At that moment I felt my heart sink. Was I in trouble? Did I do that bad that she had to stop mid-reading to tell me? What did this mean? But what she said next would be the best confidence booster I had ever had in class, and would stick with me forever.. It was my Junior year in high school, I had been submerged in homework and assignments like I was swimming in the ocean; up to my neck. I never considered myself an “amazing” writer.. There was a day where I had to do both and it was really important for a class I was taking. Mrs. Bridges’ class was one of the spoken about class amongst students. That class either made you a better writer/reader, or it gave you more work than you could handle. Of course I was nervous about taking the class, but I knew if I did succeed I would benefit from it. This day just so happened to be one of the biggest assignment days we had planned. Two quizzes and an essay due, in class. I pulled out all...

...really far away.” This was the concluding sentence of a short essay by Ian Frazier appearing in the New Yorker magazine, February 2011. You know – like mountain tops, the Grand Canyon, the Empire State Building or the bow of the Titanic (before it sank). Maynard and Stow offer remarkably few opportunities to be in a place where distant vistas are a view. Once upon a time Summer Hill, now tree-covered and trail-crossed, was open pasture. History Society pictures taken as recently as World War II show an expanse with few trees. Decades earlier, state surveyors installed an official stone marker atop Summer Hill, with the expectation that from that point, clear viewing was available in all directions. Marble Hill, at 440 feet, the highest elevation in Stow, is similarly tree-obstructed. Stow does offer a hill with a present-day view. Stories hold that ships’ pilots in Boston harbor used the stand of pine trees atop Pilot Grove Hill as a navigational landmark, suggesting that in the reverse direction a person atop the hill could see Boston’s skyscrapers. Alas, not so. Mayhap from a treetop, but not from ground level. However, Birch Hill Road, elevation 370 feet, does offer a glimpse of Mt. Wachusett, twenty miles to the northwest. Bridges can offer vistas. White Pond Road over the Assabet River, on the Stow/Maynard border, offers good views up and down river – albeit less than a mile’s length combined. The bridge is 120-feet in length with a surface 10-feet above the water...
