Wind Tunnel Measurement on a Aeroplane Model Lab Report

Wind Tunnel Measurement on a Aeroplane Model - Lab Report Example The range of the movement for the configuration will range between -20 to +100 at 10 intervals. These angles must be relative to the fuselage datum. The main function of the tail plane of an aircraft is to provide a sufficient amount of pitching moment while the aircraft is in flight and to control the aircraft in the longitudinal plane (Pankhurst & Holder, 1985). In order to achieve very efficient performance, the design of the airplane must take into consideration three important factors including; the geometrical relationship existing between the tail plane and the wing body of the aircraft, the performance of the tail plane and the structural components of the airplane (Irving, 2010). This experiment is conducted due to the need to monitor and determine the performance of an aircraft and its variation at the different stages of its movement. The results obtained will help to determine the best configuration for airplanes in order to improve their performance. The model of the airplane is mounted on an accurately and remotely operated 3 component mechanical balance. The incidence of the plane can be varied and the lift, drag and pitching moment be measured by means of weigh beams. The weigh beams usually have locks which should always be engaged when any adjustments are made to the model and also when the experiment is concluded. The balance is automatically locked when the stop button of the tunnel is pressed. Operation of the balance needs practice; the operator of the airplane must be accustomed to its natural frequencies. The forces that are acting on the plane model are lift, drag and the moment of the pitch. The airspeed can be deduced from the difference between the static pressures of the airstream at the point of entry and exit from the contractive of the tunnel. The pressure difference is usually equal to the dynamic head in the tunnel

Marie and Pierre Curie Article Example | Topics and Well Written Essays - 250 words

Marie and Pierre Curie - Article Example On top of her educational shortcomings, Curie could not speak fluent French. All of her classes were in French. Instead of giving up, Curie began studying in order to succeed. She scrimped on her food rations, rarely eating meat. Curie also did not buy coal and had to put all her clothes on top of her for warmth. All of these sacrifices were made in order for Curie to receive an education. She did end up graduating at the top of her class in physics and mathematics. The lesson in this article is students today need to have the same drive as Curie. Students today have food, shelter, and warmth. Learning for them should be easier. Despite all the obstacles, Curie did the impossible and learned. This story should inspire all students. With hard work and dedication, every student can achieve their goals. The reason students are not achieving what Curie did is the lack of drive and focus. Students today do not want to work hard for their education. The only perspective of this woman I did not like was the treatment of her child. Curie got married and had a baby, but these events did not seem important to her. Physics and being in the lab was the most important thing in her life. The role of women at the time was to be married and have children. Curie was different, but did not fight against the system. She did what was expected. Thus the roles of wife and mother were not given 100%. Curie could have done

So we prefer to do customized software development simultaneously with the required content development for the software. We also take up web portal development for our corporate clients. Here, I would like to differentiate between software development and web content development. In software development we work purely for the development of a software-base information system on a definite development platform. The information system may be web enabled.

The Swimmer Essay Example for Free

The Swimmer Essay Within John Cheerver’s, The Swimmer we can learn a lot about life choices and priorities. Cheerver demonstrates the effect of social standing in the novel through the eyes of the main character Needy. Needy has let his social standing overpower him, which eventually leads him to a life without social activity. Cheerver effectively communicates his message to the reader by combining a wide variety of symbolism and excitement. Throughout the novel the author uses a plethora of examples to display his message and even incorporates his views within the theme of the novel. A respectable theme in The Swimmer is the inevitable passage of time. This theme is clearly established through the protagonist of the novel, Needy. In the beginning of the story the author provides the reader with a clear background of Needy’s life. The information about Needy’s life is crucial to the story because it helps the reader understand and connect with the character. Needy believes that he does not have to keep in touch with his friends because the life he leads. With his high social standing, Needy believes that he is inferior to others. Life continues to pass by as Needy lives his life on the outskirts. It isn’t until it’s too late that Needy becomes aware of his surroundings and realizes he has wasted much of his life. The damage he has caused in life cannot be undone due to his lack of care and concern for others. Not only is Needy’s social life irreplaceable at the end of the novel, but he has become dependent on alcohol. It appears that Needy has grown to become his own worst enemy in life. On the contrary, Cheerver helps develop his theme of the novel through the use of symbolism. Within, The Swimmer, symbolism is frequently used as a technique to tie together the story. For example, the author portrays symbolism within the text through the multiple swimming pools Needy encounters. Each swimming pool Needy comes across represents a different time period in his life and a different group of friends Needy has known. As Needy swims from pool to pool he comes across his haunting past. Not aware of his surroundings, he continues on from pool to pool. Swimming pools arent the only symbolic object within the text. Empty houses are also part of the symbolism that is used within the novel. Needy reaches his own backyard to find an empty house with locked doors. This abandoned house becomes a symbol for Needy’s lonely and unsociable life. When Needy is at the house he finally comes to reality with his life. He finally comes to the realization that he has pushed away everyone close in his life . He has no one to talk to and feels as though he is lonely in the world. Not only does Cheerver use symbolism in his story but he also incorporates imagery. The author uses seasons as a way to help readers understand the different stages in Needy’s life. The author uses the warmer months to represent happier moments in Needys life while the colder months portray the weary and unsettling moments in his life. Seasons come and go, and so do people in our life. Needy thought that his life was untouchable, but soon came down from his cloud and realized what he had done. The theme of the inevitable passage of time truly represents the novel. People can take this story and easily connect it to their own lives. Coming from Cheerver’s past, this novel appears to be a mockery of his life. By mocking his own life, the author wants his readers to open their eyes and realize that the only thing that constantly changes is time itself. With that being said, Cheerver wanted to be a mediator for those who have started to jump into pools, and to those who have yet to jump. He warns those who have not â€Å"stepped† into the pool to step back from the edge and take a good look at what’s around them. He hopes to inform readers to never take anything for granted because nothings lasts forever.

The Respective leader ship qualities of Ralph, Piggy, Jack and Simon Essay Example for Free

The Respective leader ship qualities of Ralph, Piggy, Jack and Simon Essay On the island, all four candidates possess different leadership qualities. Although the group elected Ralph as leader, he may not be the ideal boy for the job. The fact that Ralph was holding the conch was one of the main reasons why the group chose him. They had no idea what he would be like as a leader. At first Ralph seems just like any other eleven or twelve year old, just out to have fun. He is excited by the fact that there are no grown-ups on the island, and is not bothered by it at all. Another example of his childish side is where he repeatedly cries Piggy, if only to annoy Piggy. Until Piggy correctly informed him, Ralph was oblivious to the fact that the plane they were in had crashed. This is perhaps a sign that Ralph is not as clever or as alert as other people on the island are. Soon after he is told about the plane crash, Ralph is happily and joyfully interpreting the noise of a fighter plane as it glides through the sky, shooting down its opposition. At first, Ralph is not bothered about how they will be rescued, and claims that his dad (commander in the army) will undoubtedly come and rescue them. However, Piggy soon proves Ralph wrong, and suddenly Ralph feels very uneasy and vulnerable about the situation their in. Its at this point that we see a small element of leadership in Ralph, when he orders Piggy to get his clothes for him. Like piggy, Ralph came up with some good ideas that may help them towards being rescued. He was the one who suggested they build a fire on the mountaintop. The intention was that passing boats, or even aircraft, might see the smoke rising from the island. When Ralph and Piggy found the conch in the sand, Ralph just wanted to play with it happily. He didnt realise that it could be used to round up all the people on the island. When piggy and himself gather everyone on the island together, the topic of being rescued becomes even more important. Ralph became much more concerned and less fun loving. In terms of appearance, Ralph is physically quite strong and energetic, which is a worthwhile quality for leadership. Straight away, it gained him a fair amount of respect and authority within the group, which in turn gave him more control over the group. Piggy, straight away appears a sensible and somewhat mature child. He doesnt possess the element of carelessness that exists in Ralph. Quote: searching out safe lodgements for his feet, My auntie told me not to run on account of my asthma. When most people would have run ridiculously through the creepers, Piggy takes his time and thinks about his actions. Piggy is very persisting which is a good leadership skill. He asks the same question to Ralph twice. Quote: How does he know were here? Then Piggy persists in hammering it in to Ralph, that they wont be rescued very soon. Piggy was also clever enough to realise that their had been a plane crash, and that the remains had been washed out to sea. This shows how alert Piggy is, which is another important leadership quality. In fact during the novel, Piggy is nearly always alert and responsive. It soon becomes clear that Piggy is very friendly and sociable, and he is quick to ask Ralph his name. He congratulates Ralph on his unique ability to swim. Quote: You cant half swim well. This quality is in some ways a good leadership quality, because the group will feel warmed towards him. However, if Piggy was the leader, the group might end up treating him more like a friend than a leader, and might start disobeying his orders. Because Piggy is so kind and caring, he might be a bit reluctant to stand up to people and argue with them. This is perhaps one quality that would make a poor leader. In fact, Piggy rarely gets aggressive and argumentative in the book. He is very shy, and appears afraid of the older and more dominant members in the group. In fact, throughout the book Piggy is very involved with the younger members of the group. Even so, Piggy is very clever and does come up with some good ideas. He was the one who suggested they use the conch to call everyone together. He also realised the impossibility of Ralphs dad coming to rescue them. Although, later on in the book Piggys confidence is slashed greatly and he struggles to impress the group with his ideas. Piggy is also good at judging peoples character. Straight away, Piggy was very unsure about Jack, and his immediate domination in the group. This is perhaps another good leadership quality, especially in terms of being able to understand the feelings of the group, especially the younger ones. In some parts of the book we see a slightly braver side to Piggy. Firstly, where he goes against one of his aunties rules. He goes paddling in the sea, even though his auntie told him not to because of his asthma. Another time, is when he stands up to the older members of the group, criticising them and their actions on the island. Piggys physical appearance is perhaps the main reason why he is not respected by the rest of the group, and consequently why the group doesnt see him as the leader. He is rather fat, and physically weak and unfit. He wears glasses, and couldnt survive without them, and of course he has asthma which severely ruins his physical capabilities. However, physical qualities are not always important in finding a leader and are often just a bonus. When the conch is sounded for the first time, and everyone on the island comes together, we see the arrival of another prospective leader, Jack. Instantly we become aware that Jack is very arrogant and boastful. He automatically believes he should be the leader and he becomes very dominant in the group. Quote: I ought to be chief, because Im chapter chorister and head boy. I can sing C sharp. Its very clear then, that Jack wants to be the leader of the group. He constantly gives orders out to members of the choir, and they obey him grudgingly, yet responsively. Once the whole group was together for the first time, he immediately sprung into action and commissioned himself a high authority. He announced, Weve got to decide about being rescued. When Ralph came up with the idea of building a fire on the mountaintop, the group followed Jack up the mountain, and not Ralph. Jacks ability to grab peoples attention and willingly give out orders, is a quality possessed by all good leaders. However, he can be very bossy and arrogant, and in some respects selfish, which is not appreciated by the group greatly. Respectively, his personality wouldnt make him the ideal leader, especially in terms of building a firm relationship with the group. Jack could also be described as a bit of a show off and also a bit of a know it all. During the groups first ever meeting, Jack suddenly took out a knife from behind him and through it into a tree. All this in an attempt to kill a flying insect resting on the tree trunk that he missed. Again, I think this essence of his personality doesnt make him a good leader. I think when the group is working as a team, Jack would try and do everything himself, rather than take part in a joint effort. Once Ralph is chosen as the leader by the group, simply because he was holding the conch, Jack decided he would be in charge of hunting. This is a large responsibility for a child, especially when it comes to wilfully destroying a living organism. In fact, when Jack is first faced with having to slice through the flesh of an innocent pig, he looses his bottle. It appears that Jack is not as mentally strong as he first appeared. Here we see a more caring side of Jack, which is probably very rarely seen. Jack is effected by his actions in a big way, and commits himself further to hunting. A second failure later on in the book sparks even more frustration. This time Jack throws a spear and misses the pig by far. By now Jack is very anxious to hunt down a pig, and it is on his mind night and day. When he does actually kill a pig, he fills his mind with self-achievement, honour and success. This devotion and dedication is a again a good quality for a leader to have. However, because Jack spent all his time hunting, he ended up slightly neglecting the rest of the group. He didnt help with the building of the shelters at all, and as a result the shelters were a failure. As I see it a good leader would attempt to be involved in as many activities as possible. Not only to gain control of the situation, but also to motivate the group and fill them with confidence. If Jack were a quality leader, he would have taken it upon himself to get involved with all of the groups actions. Having said that, Jacks devotion to hunting did pay off in the end, but there were still other problems on the island that needed Jacks assistance. Such as shelters and organising the group to work efficiently and successfully. Simon is probably the smallest of the four, and possibly the youngest. His first involvement with Jack and Ralph, was when they went to find out if they were on an island or not. Quote: If Simon walks in the middle of us, then we could talk over his head. This shows how Simon is smaller than Jack and Ralph. Plus, it also indicates that Simon is considered as an unimportant member of the group. They make him walk in the middle so they can talk over his head, as if Simon didnt exist. It would seem that Simon is primarily a follower, for this early part of the book. Simon automatically nodded his head to whatever Ralph or Jack said. This is probably not a good quality for a leader, especially in terms of controlling the group. I think Simon feels small compared to Ralph and Jack, and because of this, and his quiet personality, he would rarely try to dominate the group. Additionally, whilst the three were together on their exploration of the island, Simon was the first to let out that he was hungry. Although any child his age would have done the same, compared with Jack, Ralph and Piggy, he would be the weakest and most vulnerable leader. Simon is very imaginative, again like any child his age. When on the exploration with Ralph and Jack, he spots some bushes, which had candle like buds. Quote: Simon spoke first. Like candles. Candle bushes. Candles buds. This also indicates that Simon is quite intelligent and is constantly mulling over ideas in his head. Another occasion where Simon has an idea is again on the exploration trip. Ralph states that they need to draw a map of the island. Simon pops up and suggests they scratch marks on bark, and fill it with black stuff. Whether they used this idea or not, it shows that Simon is trying to be helpful, and wants to be of assistance. Another example of where Simon is trying to be helpful, is where he helps Ralph with the construction of the shelters. Simon is undoubtedly dedicated to helping the group, which is a good leadership skill. He puts in a lot of effort and works hard, even if the achievement is sometimes small. Overall, I think that all four members of the group have good and bad leadership qualities. All four of them combined would make an excellent leadership combination. However, if I had to choose one of them to be leader I would select Ralph. He is dedicated to the group. He has the ability to think of new ideas. He is physically stronger than other members of the group are. The group has a lot of respect for him, which makes controlling the group much easier for Ralph. I think Jack is just too arrogant, and he would just take advantage of leadership, which wouldnt benefit the group. Piggy would make a great leader if he was able to control the group, but his physical appearance is stopping him from doing this. Lastly, Simon is just too small and weak for leadership, and I think it would be unfair for him to take on such an important and demanding role.
