...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...

Bend your knees Squat down close to the load with your back straight and stomach muscles tight. Don’t bend at the waist. Keep the principle of leverage in mind. Keep load close The closer the load is to your body, the less force it exerts on your back. Grip the load firmly pulling it toward you.

...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”...

...OLIVER TWIST Charles Dickens Plot Overview Oliver Twist is born in a workhouse in 1830s England. His mother, whose name no one knows, is found on the street and dies just after Oliver’s birth. Oliver spends the first nine years of his life in a badly run home for young orphans and then is transferred to a workhouse for adults. After the other boys bully Oliver into asking for more gruel at the end of a meal, Mr. Bumble, the parish beadle, offers five pounds to anyone who will take the boy away from the workhouse. Oliver narrowly escapes being apprenticed to a brutish chimney sweep and is eventually apprenticed to a local undertaker, Mr. Sowerberry. When the undertaker’s other apprentice, Noah Claypole, makes disparaging comments about Oliver’s mother, Oliver attacks him and incurs the Sowerberrys’ wrath. Desperate, Oliver runs away at dawn and travels toward London. Outside London, Oliver, starved and exhausted, meets Jack Dawkins, a boy his own age. Jack offers him shelter in the London house of his benefactor, Fagin. It turns out that Fagin is a career criminal who trains orphan boys to pick pockets for him.

...Dickens’ Oliver Twist was written and published during the Victorian era, 1838. Dickens’ use of language successfully denotes contextual issues and narrative concepts, an important social commentator who used fiction effectively to highlight the contextual issues of society and class and criminality. The narrative techniques Dickens uses, unified with the context in which he wrote the novel, exemplify his ideas throughout the text. The use of good literature adds to an audience’s understanding of life during those times. It embodies thought and feeling on matters of human importance. Dickens uses the characters and situations in the novel to make a deliberate statement of his personal views of society and class about the poor laws and the criminal system. Society in Oliver Twist is hugely divided. While the upper classes live in their comfortable large houses, the lower class are seen to lead wretched lives, driven to crime by hunger and deprivation. At times Dickens steps out of the novel and addresses the reader directly using indirect speech. The opening of the book, the detached narrator impresses upon the reader that Oliver was only seen as a burden upon the parish, and also highlights the injustice of falling into a predestined social class. “The parish authorities resolved that Oliver should be ‘farmed’... be despatched to a branch workhouse where juvenile offenders against the poor-laws… ‘. He uses shifting narrative voice throughout Oliver Twist to provoke and...

...The Gift of the Magi Themes Love "Gift of the Magi" is the story of a poor, young couple whose love for each other is the most important thing in their lives. Such is their love that they're led to sacrifice their most valuable possessions to find Christmas gifts for each other. The warm home they make together contrasts with the drabness of their poverty and the dreary world outside. Their love seems to know no bounds, though Della (the wife) worries about how her sacrifice will affect her husband because of how it affects her looks. If ever there were a story with the message that all you need to be happy is love, this is it. Sacrifice The two main characters in "Gift of the Magi" are a husband and wife who give up their most precious possessions to be able to afford gifts for each other on Christmas Eve. The story seems to be all about sacrifice. We watch Della go through the process of deciding to make the sacrifice and going through with it, only to discover that her husband has made the same sacrifice. The story's narrator assures us that in their willingness to give up all they have, they have proven themselves the wisest of all gift-givers. It might remain unclear, though, exactly what their sacrifice has accomplished, or how it has affected them. Wealth In many ways, "Gift of the Magi" is a story about what it means for something to be valuable. Does something's value lie in how much money it is worth? Or are other things more valuable than money? The main characters...

...It was a bitter and frosty December morning in Boston. The year was 1765, and the Oliver family had just woken up in their small, sandy shack on the outskirts of Boston. John Oliver, who was the father of the family, was ready to walk to his carpenter shop where he worked. His wife, Bernice, was waking up the children so they could do their chores. Ralph, the older of the two sons, was angry that he had to wake up so early every morning just to do chores. Edwin, the younger brother, was annoying Ralph, so Ralph punched him in the face. Bernice told the brothers to stop bickering, and tell their father goodbye. John was ready for work, so he told his family goodbye, and he set off on his one and a half mile long stroll to work. His carpenter shop was in the middle of town. The morning began as usual until he arrived at his shop. When he arrived at the shop a tall man, who was wearing a British uniform, was arguing with Robert, a patriot friend of John, about a new tax. “You have to pay the tax or you will be arrested,” yelled the British official. Robert asked, “But, why are you taxing all of our paper products?” The official replied, “You have to help pay for the war that we helped you with.” “We did not need your help, though,” Robert replied angrily. They kept wrangling until the patriot punched the British official in the face! John had to break up the fight that had begun. Once he was successful in doing this, he asked Robert about the tax because he had never heard of it...

...As I was gathering information, I noticed that geographic determinism and lyrical pastoralism could go hand in hand. Reading the story made me feel like the land was beginning to represent the emotions of the two characters. After Ennis and Jack have an argument about what they want to do with their relationship, Annie Proulx writes, “Like vast clouds of steam from thermal springs in winter the years of things unsaid and now unsayable—admissions, declarations, shames, guilts, fears---rose around them” (42). Ennis is the more masculine character between the two, and he does feel ashamed of the relationship, he hates what it is, and he is afraid of what can happen to him. Unlike other movies where, usually in the background we see other supporting...
