...Purdue University Calumet College of Technology Department of Mechanical Engineering Technology MET 21100 – Strength of Materials Torsion Lab Experiment Performed: 4/3/14 Report Due Date: 4/17/14 Report Submitted: 4/17/14 Joshua Deakin Prepared for Aaron Kolb Introduction: In the designing of buildings and structures, torsion, or torque could be applied to certain members. Most times, torsion is found at almost all times in a vehicle, on each axle, the driveshaft, and many others parts in a vehicle. These members all need to withstand the angular moment or load that is acted on it. You do not want to step on the gas, and your driveshaft or axles snapping. You wouldn’t be going anywhere anytime soon. The torsion test primarily measures, at a certain moment or load, how much the bar or specimen is twisting and at what angle. This test can also be done in reverse order measuring the angle first, and recording the torque on the test material. The testing of a “torque-angle” graph can be somewhat similar to a “stress-strain” curve. There are a few different types of torsion tests * Torsion only: applying only a torque (what we had done) * Axial-torsion: Applying and axial, as in tension or compression, and a torsion force to the specimen * Failure: applying the load until the specimen fails, which includes a physical break, kink or other defect in the specimen * Proof: In this test, you apply a torsion and hold that force for an extended period...

...is to assign a specific exercise to each suit. The example Barnhart uses is “hearts are pushups, clubs are squats, spades are bicycle crunches, and diamonds are mountain climbers”. The number on the card is the amount of reps you have to do, face cards count as 10 reps and aces count as 11. The second excise Barnhart talks about is the lunge and twist. The lunge and twist focuses on the legs (hamstrings, quad, glutes), but when you add the twist it helps develop core strength, proprioception, and balance. The lunge and twist starts by holding a dumbbell the long-ways between both at about chest high and close to the body. After you are in position you perform the lunge, “If you lunge forward with your right leg, at the apex of your lunge, rotate your torso to the right side. Hold for one to three seconds. Return to the original position and then repeat with the left leg”. Barnhart has two ways that he recommends to do the lunge and twist, the first way is to add three to four sets to the lunge and twist , performing 12 to 15 reps with a low weight dumbbell (5 to 20 pounds maximum). The second way is to perform as many lunge twists as you can in a 30 to 45 second interval, then rest and repeat one to two more times. The third excise Barnhart talks about is push up jacks. The pushup jacks are designed to build stamina and endurance in the upper body as well as the lower body. The pushup jacks are started by beginning in standard push up position and do a regular push up...

...Length Box Braids The Pros and Cons of Mini Twists for Natural Hair 45NATURAL HAIR CARE PROTECTIVE STYLING by Chinwe – January 31, 2014 Share Button Pin It minitwist5 (Circa 2010) By Chinwe of Hair and Health Mini twists are essentially tiny twists, much smaller than the diameter of a pencil. In some cases, mini twists are so small that the hair may appear loose rather than twisted. THE GOOD: Mini twists last longer — anywhere from three to six weeks — than larger twists. Because they are so small, they tend not to frizz and age as quickly. This is great news for those who want to leave their natural hair alone for several weeks at a time. Not only do mini twists last longer, they also allow for more versatility in styling. Because they are so small, it is much easier to achieve a range of styles than with larger twists. A lot of the styles can mimic those on loose natural hair. minitwist1 (In 2013) THE NOT SO GREAT: Mini twists can take hours to a day or two to install or take down. This can be a challenge if you have to be somewhere or you just do not have the time or patience. In terms of helping with patience, watching a few movies or television shows can help pass the time. When it comes to needing to be somewhere, some naturals prefer to start their mini twists in the front or along the perimeter of their hair so that they can “fake the finished look” if they haven’t completed the twists in time. THE BAD: Single-strand knots...

...The life he builds, which involves financial hardship and eventually child support, effectively prohibits him from escaping. Ennis is a prisoner of the life he has been born into. Without the financial wherewithal to escape, without any sort of community support for his sexual proclivities, and imbued with the belief that one must bear whatever one can’t fix, Ennis is fated to live out the rest of his life as a man who tasted happiness once but has never again reached that peak. Though it is Jack Twist who, we infer, is murdered by those who oppose his sexual orientation, it is Ennis Del Mar—living in his trailer, confined to a sad life on the broad, flat plains of Wyoming—who is the story’s tragic soul. Jack Twist Jack Twist is the more verbally aggressive and outgoing of the story’s two main characters. His name is onomatopoetic in its quick, light-footed sound, the clarity of its consonants strikingly dissimilar to the marbles-in-mouth quality of “Ennis Del Mar.” Jack Twist is flashy and brazen, a would-be rodeo star, and later a glitzy Texan transplant who sports a brass belt buckle and large capped teeth. He is far less...

...Charles Dickens In Charles Dickens’s Oliver Twist Nancy prepares to escape from the torment of Bill Sikes, not realizing she is being followed by a subordinate of Sikes. She meets Mr. Brownlow and provides details about Monks, letting him know that she intends to help Oliver escape. This information is relayed to Sikes and shortly thereafter, Nancy is beaten to death. Nancy is a morally ambiguous character who wrestles with making the right decisions. She serves as a common Dickens character who tries to do right but gets crushed by a cruel world. In Dickens’s world, people grow and change over time and can be easily influenced by the world’s vices. People enter the world innocent and rational, but as they age, society seeks to break them. Still, Dickens believes that some, like Nancy, can free themselves from society’s influence and become more compassionate. Dickens lauds those who reflect the created order by showing concern for the needs of others, regardless of social standing or background; he also believes that humans can become corrupted by the world, so discovering inherent goodness is a struggle. People enter the world innocent and rational, and society quickly preys on them. Society strives to form each person into what it wants, changing how people grow over their lives. Scrooge of A Christmas Carol was once compassionate towards others and becomes hard-hearted after tragic events. He lost a sister and grew stingier, driving those in his life away. He comes to...

...An Analysis of Longfellow's A Psalm of Life Henry Wadsworth Longfellow begins his poem "A Psalm of Life" with the same exuberance and enthusiasm that continues through most of the poem. He begs in the first stanza to be told "not in mournful numbers" about life. He states here that life doesn't abruptly end when one dies; rather, it extends into another after life. Longfellow values this dream of the afterlife immensely and seems to say that life can only be lived truly if one believes that the soul will continue to live long after the body dies. The second stanza continues with the same belief in afterlife that is present in the first. Longfellow states this clearly when he writes, "And the grave is not its goal." Meaning that, life doesn't end for people simply because they die; there is always something more to be hopeful and optimistic for. Longfellow begins discussing how humans must live their lives in constant anticipation for the next day under the belief that it will be better than each day before it: "But to act that each to-morrow / Find us farther than to-day." In the subsequent stanza, Longfellow asserts that there is never an infinite amount of time to live, but art that is created during one's life can be preserved indefinitely and live on long after its creator dies. In the following stanzas, Longfellow likens living in the world to fighting on a huge field of battle. He believes that people should lead heroic and courageous lives and not sit idle and remain...

...Oliver Twist written by Charles Dickens Oliver Twist published in 1838, a novel written by Charles Dickens, who was a leading English novelist of the Victorian ear and also considered of being one of the greatest English writers with deep-storytelling novels. ``Oliver Twist``, Dickens second novel, tells the story of the orphan Oliver who is through unfortunate circumstances forced to take part in criminal acts of the gangland of London. Where from he is later on rescued. I decided to analyse how Dickens tried to describe and expressed the poverty and the abundance in his novel, in doing so I will also try to direct my attention on the conditions of life at that time in England. To clearly understand you have to know how England was looking like around 1830 – also called the Victorian ear. In the 19th century more and more people moved into towns, with intent to find work. Cities like London were not prepared for such crowed of people and overcrowded very fast. And with the crowing number of people the living standards went down. So it was normal that a whole street had to share toilets and water. On the other hand there were the rich, which had bigger houses with fluent water and underground sewers. Dickens is showing in his novel all the time the two, to this time ruling standards of life, and Oliver Twist performs as his character who walks between and tries to reveal them. On the one side there is Mr. Bumble, the beadle, his job is to administrate the finances of...

...Kevin Rojano Mr. Belasco AP Literature 17 September 2015 Three Girls Plot Analysis The plot in “Three Girls” was very misleading. The narrator told a story of her and her friend’s encounter with Marilyn Monroe. What the story was really about, was the narrator's first kiss with her friend. This twist ending was an eye opener for the rest of the passage, as hidden clues became obvious signs. There were many clue pointing towards the twist ending that were identified after the plot had developed. We were lead to believe that it was story about how they have encountered Marilyn Monroe in their favorite bookstore. The significance of Marilyn to the real plot was that she was something that the two girls could bond over. Marilyn was their “thing” and they did not not want anyone else in on it. Scattered along the path of stalking and helping Marilyn, the narrator speaks affectionately about her friend. She comments on her body shape and monkey nimbleness which before seemed like meaningless comments. There were other clues like the use of “enchanted” several times to properly set the mood for the story. The way the plot and ending came together helped understand these clues. The surprise ending in “Three Girls” tied the entire passage together. It helped me understand that the story was one of a first kiss. The flashback transformed from a celebrity encounter to a romantic experience. It was a cute memory but it made sense of the “persevering author and married with kids”...

...The Green Arrow ‘s real name is Oliver Jonas Queen. His parents are Robert Queen and Moira Queen, who were mauled by lions in a tragic safari accident. Before the death of his parents, Oliver was mildly traumatized when he accidentally killed an animal, and when his parents were being mauled by the lions, Oliver’s hesitation to shoot cost them their lives. With that being said, there is no known medical conditions or any reported use of medications for any mental issues. After the death of his parents, Oliver Queen inherited the family fortune and business. Queen lived his life how he wanted and never gave back to society. He grew into a rich, spoiled, thrill-seeking playboy until he was left stranded on a deserted island for serval years. He was presumed dead and lost at sea, but he had, in fact, survived and was lost in a deserted island known as Starfish Island. After his return home, Oliver Queen used his new skills and wealth to become the Green Arrow. The Green Arrow became a member of the Justice League of America. Green Arrow began to develop a personal crisis about which was more important and actually doing good, the crime-fighter, Green Arrow, or the politician, Oliver Queen.

...Oliver Twist in relation to the Newgate Calendars Born into a poor English family in 1812, Charles Dickens worked his way up from a life of poverty and debtor's prison, to become a writer of national acclaim. In his Victorian era, he was an exception to the rule because it was very difficult to break through the barriers of social class and better oneself. Because of his bleak childhood, Dickens was one of the few writers of his time who could express the horrors of society as they really were. One of his most famous novels is Oliver Twist. This story centers on a young boy named Oliver whose real identity is unknown when his mother dies in childbirth. As an orphan, he is exploited by corrupt and selfish authority figures, and is forced into a life of poverty, hard labor, misery and crime. Oliver suffers horribly and often takes the blame for others' misdeeds. Dickens is showing that Oliver is a good person, and the bad things that happen to him are through no fault of his own, but because society and the people around him are bad. From his earliest childhood days, Oliver is treated harshly by society. He was born in a workhouse where he is barely given enough food to live and is forced to do hard manual labor. Dickens satirically describes the authorities' view of the poor in this passage: "'Oho!' said the board, looking very knowing, 'we are the fellows to set this to rights; we'll stop it all, in no time.' So they established the rule that all poor people should have...

...Finally identified, the real Oliver Twist workhouse reveals stories more brutal than even Dickens dared tell By Dr Ruth Richardson UPDATED:11:49 GMT, 25 March 2011 Please sir: Oliver Twist brought home the harsh realities of life in the workhouse The young woman at the workhouse gate was desperate. Clutching her belly, she begged to be allowed inside. She had nowhere else to go. The workhouse — for all the stories of cruelty that went on within its walls — was her only hope. She desperately needed shelter, for she was about to give birth. But the gatekeeper was inexorable: he had his orders. Babies were expensive. They required feeding, clothing and supervising and it would be at least six years before they could earn their keep, either in the workhouse or in factories, mills or up chimneys. The workhouse authorities had a duty to care for mothers in such a desperate plight. They were paid by the parish to house and clothe the wretched men, women and children who came to their doors as a last resort. For few would reside in the workhouse by choice. The conditions made prison seem comfortable in comparison. But the Beadle — the supervisor of the workhouse — cared less for the law than for his own pockets. He could make a small profit from able-bodied adults and children by setting them to work outside the workhouse, while he siphoned off some of the money that was supposed to feed them. Babies, on the other hand, were not profitable. The workhouse gate clanged shut...

...Oliver Twist is one of Charles Dickens’ most famous novels and a classic poor-to-rich story about an orphan who was born into a workhouse and must navigate his way around the criminal underworld to avoid being corrupted. Literature incorporates the history of the workhouse and reflects the concerns of both paupers and ratepayers, and it also challenges the dehumanizing effects of the Law’s administration. The time period of Oliver Twist was still under the time of the Old Poor Law, but it was mainly seen as criticizing of the New Poor Law. Felix Driver writes, “The account of the starving child who asked for more was almost certainly based on the earlier system, although the extent to which the old survived in the new does not entirely invalidate the criticism”. Scholars tend to focus on the scene where Oliver asks for more food as indicative of the meagre portions that the inmates received. These scholars identify hunger as the main threat of the workhouse, but that approach neglects the larger threat of death, which shapes Oliver’s character. When the opening chapters of the novel are considered more broadly, the workhouse is actually a site where the poor carry an obligation to one another. High death rates within the workhouse encourage solidarity as seen by the behaviours of the orphans. While providing charity carries the risk of supporting idlers, and Dickens is consistently critical of charity, he also writes the poor as recognizing common risks and finding their own...
