School Shooting Massacres Essay Example for Free

School Shooting Massacres Essay Background: A school shooting is an incident in where gun violence occurs at an education institution. A school shooting can affect the students and workers who were in the shooting mentally and physically. The earliest known school shooting to ever take place in the United States was the Pontiacs Rebellion school massacre which happened on July 26, 1764. In this school massacre, four Lenape American Indians entered the school, shoot and killed Enoch Brown, and killed nine or ten children. It is either nine or ten because the reports can be shifted and changed. Only three children survived. There have been worst serious cases where a shooting had managed to take the lives of a couple of people. The Virginia Tech Massacre which was on April 16, 2007 was one of the deadliest shooting incidents by a single gunman in U.S. history. It lasted between 7:15 a.m.–9:51 a.m. The gun man was Seung-Hui Cho, who was a senior at the time in Virginia Tech. Thirty-three people were killed including the gun man himself and twenty-three were injured. This massacre influenced media coverage and drew widespread criticism of U.S. gun culture. It also talked about how there were gaps in the U.S. system for treating mental health issue because Seung-Hui Cho was mentally unfit. The shooting was also known as the second-deadliest act of mass murder at a US school campus. The Columbine School Shooting took place on April 20, 1999. It lasted between 11:19 am – 12:08 pm. The gunmen involved were two seniors named Eric Harris and Dylan Klebold. The shooting was mostly focused on school bullying and cliques at school. This school shooting had a very good chance where it could have been stopped. Erick Harris created a blog on a page for a video game where he talked about school, friends and family. It also included the information on how to create trouble and how to make explosives. The blog also talked about the trouble that they were going to cause. It also included how much they both hated the people who bullied them and society itself. The Sandy Hook shooting took place on December 14, 2012. It lasted between 9:35 am – c. 9:49 am. The gunman was Adam Peter Lanza. The reason for the shooting is unknown since the gunman killed himself. Twenty-eight victims were killed and two were injured. The Shooting is the second deadliest shooting in United States history. It is also the deadliest mass murder in an American elementary school. The shooting started debate on gun control and a new idea for banning the sale and making of some types of semi-automatic weapons and magazines. Adam Lanza also killed his mother at home by shooting her and taking her guns to the school. Adam’s Lanza’s brother also told law enforcement that he was â€Å"somewhat autistic†.

Fall of Usher :: essays research papers

"The Fall of the House of Usher" Summary The narrator approaches the House of Usher on a "dull, dark, and soundless day." This house--the estate of his boyhood friend, Roderick Usher--is very gloomy and mysterious. The narrator writes that the house seems to have collected an evil and diseased atmosphere from the decaying trees and murky ponds around it. He notes, however, that although the house itself is decaying in pieces (for example, individual stones are disintegrating), the structure itself is fairly solid. There is only a small break in the front of the building from the roof to the ground. The narrator reveals that he is to stay in this house because his friend, Roderick, sent him a letter earnestly requesting his company. Roderick told the narrator in this letter that he was feeling bodily and emotionally ill, so the narrator rushed to his house. The narrator also mentions that the Usher family, while an ancient clan, never flourished. Only one member of the Usher family survived from generation to gener ation, so they were all in a direct line of descent without any siblings. The inside of the house is just as spooky as the outside. The narrator makes his way through the long passages and to the room where Roderick is waiting. The narrator notes that his friend is paler and less energetic than he once was. Roderick tells the narrator that he suffers from nerves and fear. His senses are heightened. The narrator also notes that Roderick seems afraid of his own house. Further, Roderick's sister, Madeline Usher has taken ill with a mysterious illness that the doctors cannot even identify. The narrator proceeds to spend several days trying to cheer Roderick. He listens to Roderick play the guitar (and makes up words for his songs), he reads to Roderick, he sits with him for hours. Still, he cannot lift his sadness. Soon Roderick posits his theory that the house is unhealthy, just as the narrator had supposed at the beginning of the story. Soon, Madeline dies, and Roderick decides to bury her temporarily in the tombs below the house. He wants to do this because he is afraid that the doctors might dig up her body for scientific examination (since her disease was so strange to them). The narrator helps Roderick put the body in the tomb. He notes that she has rosy cheeks, as some do after death.

The Clifton Suspension Bridge

FunctionThe Clifton Suspension Bridge was designed by Isambard Kingdom Brunel and completed in 1864. The span spans 214m across the Avon Valley Gorge from Clifton to Leigh forests as shown in figure 3. The towers are 26.2m high and the span concatenation has a breadth of 6.1m Centres to center. There are two vehicle lanes and two prosaic waies. The prosaic paseo is to boot used as a sing topographic point along the Avon gorge. There are about 10,000 autos traversing per twenty-four hours with a gross vehicle weight bound of four dozenss. The toll for the span is presently 50p ( 27/11/09 ) . Bing an historic span, the construction requires changeless services which the tolls fund. The velocity bound on the span is presently 15mph and the weight bound is controlled utilizing a modern weight beam ( Mitchell-Baker, D. Et al 1988 ) . The span was designed to originally take the weight of Equus caballuss and passenger cars. The site location was chosen because of its short and flat span.St ructureThe span takes the signifier of a convention suspension span. This signifier was ambitious at the clip of design and if it was completed on agenda it would hold been the longest suspension span in the universe. The suspension span was a suited pick for two chief grounds. The first ground is that the tallness between the deck and the river below is 75m and to build a tower would be expensive. It besides would hold been expensive to build any signifier work. A suspension span can be constructed without the assistance of signifier work and Brunel ‘s design did non necessitate a tower compared with Telford proposal which included two Gothics styled towers ( Moore, Fuller. 1999 ) . The 2nd ground is that the strength of the environing topography allowed the being of ground tackles. In state of affairss where a suspension span would be suited, the status of the land is unsuitable for bearing the force per unit area from the overseas telegrams. One of the disadvantage of utili zing a suspension span on the site is that it can merely be a individual span. The ground tackles have to take the entire tenseness of the concatenation compared with a three span span where the deck on the side span acts as a counter weight, alleviating tenseness in the ground tackle. The construction is formed chiefly of a long concatenation, similar to a motorcycle concatenation, two towers and the span deck. As it is shown in figure 5 the concatenation is formed of three sub-layers on each side, each bed dwelling of an jumping 10 and 11 level wrought Fe bars. By increasing the figure of concatenation beds the overall opportunity of prostration lessenings. The level wrought Fe bars were designed to be every bit long as operable. The long bars decrease the entire weight of the ironss by cut downing the sum of heavy articulations. . By increasing the sum of ironss, the construction becomes less reliant on each person concatenation ; hence failure of a concatenation should non take to prostration. The dip to cross ration of the ironss contribute to the efficiency of the construction. High span to depth ratios cause high tenseness in the concatenation, this is because of the way of the concatenation reacts about perpendicular to the weight, making an inefficient construction. Low span to depth ratios do a more efficient concatenation but the tallness of the towers have to increase hence increasing the cost. The most effectual span to depth ratio is about 1:10 which is what was adopted by Brunel for the span. This is an betterment to the 1:13.5 ratio which Telford antecedently adopted on the Menai span. The chief catenary ironss are non attached straight to the deck at mid span ; this is done to let the chief deck to hover freely in the air current without seting strain on the ironss ( Pugsley, Sir A. 1976 ) , ( Porter G. 1974 ) . Hanging at 8ft intervals are the shaped Fe rods, which transfer the burden onto the concatenation. The array of rods is designed to oppose prostration if a individual rod should neglect. The rods are attached slackly between the concatenation and longitudinal girder, see figure 5 ; this allows motion which decreases the opportunity of failure from span motion. This so imposes a perpendicular downward force onto the towers and tenseness along the concatenation and in the ground tackles. The longitudinal girder as shown in figure 5, is a uninterrupted stiffened I beam. The girder is 3ft deep and connects the cross girder to the rods. The original design proposed by Brunel used a timber lattice girder with a matching stiffness, but by the clip of the Bridgess building the lumber lattice was replaced by an Fe plated girder. The girder takes the emphasis applied to a individual articulation on the concatenation and traverses it along the longitudinal length of the concatenation. As illustrated in figure 4, a truss construction is adopted for the cross girders. The truss construction is a really strong and efficient construction along the length. The shallow deepness allows thin strips to organize the trusses without clasping. The place of the cross girder is shown in figure 5. The cross girders are braced horizontally utilizing thin Fe strips to respond against air current burden. The quadrangle form deforms under burden by rotary motion at the articulations. The brace forms a triangular molded construction ; distortion in the triangular molded construction occurs by flexing of each member, therefore increasing the elements stiffness. Live tonss are transferred onto the lumber beams which span between each cross girder ; using a perpendicular burden and doing a bending minute in the girder. The lumber decking was chosen because it was light and suitably strong ; it besides allows easy accessible fixs. A shaped Fe adorning frame was added by Barlow and Hawkshaw to increase rigidness. The saddles are situated on top of the towers. The saddles allow sidelong motion of the ironss. Lateral motion occurs due to temperature alterations or unsymmetrical burden. The saddles besides allow the perpendicular emphasis to be reduced in the rock tower by increasing the contact country, understating the hazard of oppressing the rock. The ground tackles are 17m below the land and the ironss are spread into a chamber to make a stable foundation. The spreading of the concatenation allows the tenseness to be opposed by the compaction of the drop, non entirely trusting on the clash. The advantage of this is that the strength of the ground tackles increases ; it besides takes advantage of the strong limestone foundation. ( Pugsley, A. 1976. )StrengthThe constructions weight bound for vehicles is presently four dozenss. This weight bound was introduced about 50 old ages ago when applied scientists decided that the big tonss and weariness could take to fall in. The sum of vehicles on the span at one clip is controlled by the toll booths. This is done to cut down the entire burden on the span at any minute. Brunel designed the span to defy an adventitious burden of 100lbf/sq.ft which is about equal to 4.7 KPa of force per unit area ( Porter G, R.F.D. 1974 ) . . This is simular to the unrecorded burden which is adopted on modern Bridgess with similar spans ( Bangash, M, Y, H. 1999 )ConstructionAfter planing the span, the foundations and abutments were the first elements to be constructed. Then the towers were the following thing to be constructed. The ironss were pulled across by rope and so the deck was attached to the concatenation.CareBetween 1864 and 1953 the lumber decking had been replaced three times and the ironwork had been treated twice and at the terminal of this period was still in good status. Two suspender rods had failed in a terrible storm in 1877 and three more had failed in 1887. Both occasions the exact cause of the failure is still non convincingly known. In 1861 a 6 metric ton vehicle weight bound was appointed to the span. The size and weight of vehicles was continuously increasing and applied scientists were concerned with the Bridgess construction. It was based on the theory that repeated lading on metal causes its hempen construction to go crystallite. In 1918 one every 10 bolts from the rods were removed for proving, and they were all found to be of equal strength though some cleft appeared ; these clefts were likely to happen from hammering. The drainage of the span had caused serious corrosion to anchor degree ironss. In 1925 an excess nexus was added to the ironss but there were still concerns for the ground tackles status. To get the better of this concern concrete was poured to a deepness of above 9ft above the ground tackle. In 1953 the duty of the span was passed to the trusses and the national heritage. The point burden of wheels was known to be more detrimental to the deck than to the construction as a whole, doing the deck to be once more in a terrible status. The weight bound was so changed from 6 ton bound to 2.5 ton axle weight and 4 ton vehicle weight. ( Mitchell-Baker, D. . Cullimore, M. S. G. 1988 ) In 2009 a prosaic noticed a serious cleft in one of the suspension rods and the closing of the span followed. Impermanent supports were put in topographic point while the rod was replaced. A twelvemonth earlier work to better the sealing, drainage and new route surface was completed. This would diminish the sum of corrosion of the Fe work. ( BBC News. 2009 )AestheticssThe span is really aesthetically delighting, it has few single elements, and each component is similar in map. The girders are really thin and it has a uninterrupted span which besides makes it more appealing to people, most people would hold the span is beautiful. The form of the construction besides reflects the force applied to it, being dilutant in the center and thicker as it gets towards the borders where the greater minutes would happen. The span besides has a bold and dramatic lineation when viewed from along the vale ( Gottermoeller, F. 1998 ) . The towers are curved so that they appear tall from below, organiz ing a bold construction. The towers are besides in good proportions compared with the immediate surrounding and harmonious in three dimensions. The span is constructed utilizing locally sourced stuffs, incorporating the construction into the environment. ( Chen, W et Al. 1999 ) . The span is 3ft higher on the Clifton side. This is done to halt the semblance that the span deck is falling towards the drop.
