Material Selction Essay Example for Free

Material Selction Essay Park bench A park bench isn’t just for parks. It is an essential component of any public outdoor (or indoor) area. The 3 material I chosen ( wood concrete steel) These park benches provide strength and durability with a strong steel skeleton and high quality UV and weather resistant thermoplastic coating. One of the most popular bench styles, the thermoplastic coated steel park bench comes in a range of styles and colors. The thermoplastic coating protects the steel for years to come, and is maintenance and corrosive free. Made for the widest range of applications, these benches can be portable as well and permanent installs. Commercial park benches made with wood are always a top seller. Made usually of cedar, or pine, wood park benches offer strength and durability, reinforced with a welded metal frame construction for a long life. Wood is the popular choice also for its classic styling. When people think park bench, they will more than likely visualize a wood slat park bench with back and arms in an unfinished cedar nestled in a shady spot under an oak tree. This is obviously a great solution for a park, or outside of a mall but I would not recommend it for any city transit area. Other materials, like powder coated steel are better performers for high traffic. Concrete Park Benches are an inexpensive solution to a high traffic area. Dense and strong, anything concrete will last a long time and is ideal for parks, schools, bus stops, corporate break areas and rest stops, and other various street scapes or public areas. It is also resistant to vandalism and thievery due to its inherent density and bulk. It would be strenuous to attempt to move or damage one of these, making a concrete park bench the perfect solution for a permanent install. Hip joint The human hip is a ball and socket joint. This means that the top of the leg bone, the femur, is rounded and fits into the socket of the hip. This joint may need to be replaced if it has worn away, broken, or become chronically painful in some way. The process involves replacing the hip joint with 3 artificial parts, cup, ball, stem: Cup The cup is the most vital part of the hip joint process as the other 2 parts is dependable on the cup being good thus the material must not only be tough and strong but resistant to corrosion, degradation, and wear-.I chose the material ultra-high density polyethylene for the cup component in because of its outstanding toughness cut and wear resistance and its excellent chemical resistance. Fermoral ball – I chose the ceremaric material Zirconia for the head (ball) component in because of its Strength and Longevity, Zirconia is virtually indestructible ans should last a life ti. itcan be polished to give a very smooth surface and have a much lower wear rate than metal on polyethylene. Also using ceramics over metals for hip replacement parts are to do with the inherent biocompatibility of ceramic materials. Being highly oxidised, they are very inert and so the risk of any reactions with the host is negligible. However As with everything in life, all these benefits come with a price. Zirconia is very tough, which is good until you consider the abrasive effect of the material against the other compnenets. Fermoral stem – I chose the alloy material titanium for the stem component because not only does it have the combined properties of being light and strong it also allow for movement of the artificial hip joint with a minimal amount of friction. In addition, titanium are long lasting, strong and resistant to corrosion, degradation, and wear. Therefore, they will retain their strength and shape for a long time. Resistance to wear is particularly significant in maintaining proper joint function and preventing the further destruction of bone caused by particulate debris generated as the implant parts move against each other. However titanium is quite expensive.

The Cave and the Matrix Essay -- Plato Republic Matrix Movie Philosoph

The Cave and the Matrix Movie critics and philosophers alike agree that the movie â€Å"The Matrix† is indeed based upon certain Platonic themes from Book VII of The Republic. In this story entitled "The Allegory of the Cave," he describes a dark underground cave where a group of people are sitting in one long row with their backs to the cave's entrance. Chained to their chairs from an early age, all the humans can see is the distant cave wall in from of them. The shadows of statues held by unseen ‘puppet handlers’ reflect on the walls from the light of a fire that is also out of sight of those in the cave. The theme of the allegory is that their reality is a poor copy of the real world. According to Plato, our world is nothing but shadows, imperfect manifestations of the forms. Similar to the prisoners of the cave, the humans trapped in the matrix (the cave) only see what the machines (the modern day puppet-handlers) want them to see. They are tricked into believing that what they hear in the cave and see before them is the true reality that exists. Furthermore, they accept what their senses are telling them and they believe that what they are experiencing is all that really exists--nothing more. The movie not only incorporates these same ideas, the story line of the movie parallels that of the allegory. The most important character is who Plato calls the â€Å"Philosopher† or the â€Å"Intellectual.† In the allegory, Plato hypothesizes that one of the prisoners eventually be rel...

Essay on Shakespeares Macbeth as Tragic Hero - 623 Words

Shakespeares Macbeth as Tragic Hero Shakespeares Macbeth follows the journey of nobleman Macbeth that starts with him as Thane of Glamis and ends with him as King of Scotland. Macbeth is a tragic hero because he possesses all the traits that Aristotle outlined in his poetics. He said that the tragic hero must be a man that is higher than mortal worth, but has tragic flaws.

Macbeth is a nobleman and a warrior and therefore, it is important for him to be manly in front of everyone, which is why he is insecure about his manhood. Lady Macbeth plays on this insecurity and is able to control Macbeth through this manipulation. She challenges his manhood when he decides not to kill Duncan, saying When you durst do it, then you were a man (I, 7, 54). This pushes Macbeth to kill the King. Lady Macbeth also challenged his manhood when he sees Banquos ghost, saying that if he were a real man, the sight of a ghost would not bother him. ...regard him not--Are you a man? (III, 4, 69) Macbeths reliance on the prophecies was another important factor in the decline of his character.
