The Physics Of Continuum Mechanics - 763 Words

In continuum mechanics, a Newtonian Fluids is a fluid that the viscous stress arising from its flow, at every point, are linearly proportional to the local strain rate. The reason we research Newtonian Fluids is that Newtonian fluids are the simplest mathematical models of fluids that account for viscosity. In natural world, there are many common liquids and gases that can be assumed to be Newtonian Fluids. For example, water, alcohol, thin oil, air, and most of pure liquids. Newtonian fluids get the name by Isaac Newton, who is one of the most famous scientists in the world. He is the first person who found the relation between the rate of shear strain and shear stress for such fluids in differential form. Newtonian Fluids can be also called linearly viscous fluid, which has been found to describe adequately the mechanical behavior of many real fluids under a wide range of situations. In order to study Newtonian Fluids, we need to understand the concept of fluids. A liquid is a nearly incompressible fluid that will suit to the its container’s shape. However, its volume always independent of pressure. There are four basic states of matter. They are solid, gas, plasma, and liquid. Besides, Liquid is the only state with a definite volume but no fixed shape. Water is the most common liquid on Earth. Liquid and gas are similar in many ways. Both of them can flow and take the shape of a container. However, most liquids cannot be compressed as others. Also liquids will not toShow MoreRelatedThe Quantum Relativistic Mess899 Words   |  4 Pagesactive theoretical frameworks in particle physics that is used in an attempt to successfully reconcile general relativity and quantum mechanics.

One of the five drafters of the Declaration of Independence. This vast array of contributions by Benjamin Franklin leaves no wonder as to why his face is on the $100 bill or a namesake to many commercial establishments and schools today. His prevalence in todayrs society serves as a constant reminder of his commitment and service to the American people. Many of us know Benjamin Franklin as one of the most well-rounded and revered men in American history. He was a blacksmith, printer, writer, scientist, inventor, diplomat, politician, Freemason, and founding father of the United States of America. His vast expanse of knowledge stemmed from his intellectual curiosity, some of which came from an internal drive and some from the period of Enlightenment thought. While this inquiry led him into these many fields, none have so highlighted his desire to serve those in his community like his experiments and inventions in science. His selfless demeanor shined as a beacon during a time when 18th-century America was struggling and in need of a leader; it was these inventions of Benjamin Franklinrs that helped secure his role in politics and as the future founding father of America. Don’t waste time! Our writers will create an original "Benjamin Franklin: An American Hero" essay for you Create order Born on January 6, 1706, in Boston, Benjamin Franklin was the eighth child of Josiah Franklin (1657-1745) and Abiah Folger (1667-1752). While his mother was from Nantucket, his father was an immigrant from England, arriving just 23 years earlier. Benjamin grew up in a deeply religious family†he was baptized on the day of his birth. His father even offered young Benjamin as a tithe to God and had him attend Boston Grammar School. However, upon learning of Benrs intellectual curiosity and limit-pushing nature, Josiah decided to withdraw him and have him attend Brownellrs English School. Attending school turned out to be a challenge because the Franklinrs had ten children to take care of, so they had Ben working as an apprentice for his father by the age of 10. Again, he found a growing discontent as a blacksmith and felt a strong urge for the sea. It must be noted here that a portion of Benrs quizzical nature must be attributed to Josiah himself, as he enjoyed having people ov er for dinner at the Franklin household to stimulate his childrenrs minds. Having done so much so, Josiah tried to appease Ben by letting him explore other options. Young Benjamin loved books, and this desire to read and learn translated to printing where he served for nine years as an apprentice to his older brother James at a printing house. Ben liked the mechanical and manual challenges of the job, which required critical and analytical thinking to solve. He also saw how the power of words could transform and broaden oners mind; this later served as an outlet for his writing. Ben even published some works in The New England Courant, a journal of his brotherrs printing company. Through this, he was able to express his wit and satire on topics such as politics, religion, education, womenrs rights, and freedom of speech. One day, however, James was taken to jail on account of offence to the Assembly. From his jail cell, he wrote to Ben (then 17) that he was to take over as editor, which meant having to break Benrs original apprenticeship contract. However, James mentioned another secret one. Feeling bound by this contract, Ben took the oppor tunity to go out and explore. He first went to New York City until he realized that he could not find a job. He then went to Philadelphia and worked at a smaller print shop, slowly working his way up the ranks until he wound up as a pressman and compositor in a major print shop. One day in 1724 he went to London because the company needed him to get supplies, but the owner failed to give him letters of credit, so Ben ended up staying in London for a year and a half. Upon his return in 1726, he worked for a couple of print shops until he started his own (The Pennsylvania Gazette, which the first political cartoon Join, or Die was published) in partnership with Hugh Meredith. As his credibility in the printing world was gaining, so was his image as a public figure. In 1727, he formed the Junto, a club aimed at discussing morality, politics, philosophy, and business. Ben even became the official printer of Pennsylvania in 1730 and bought out his partner. That same year he married Deborah Read (1707-1774) through a common-law marriage. The couple had two children together: a son, Francis (born 1732, died 1736) and a daughter, Sarah (1743-1808). Ben also had an illegitimate child, William Franklin (1731-1818), who would later become the Royal Governor of New Jersey. The same year his first son was born, Ben joined the Freemasons and began his period as an author, writing Poor Richardrs Almanack until 1758. The rewards did not stop coming for Ben Franklin. In 1736, he was appointed as clerk of the Pennsylvania Assembly and a year later was named official postmaster for Philadelphia. His time as a politician was on the rise, but it was his initial interest in science in 1743 that helped jumpstart his lifelong career in service to the American people.

Disaster Management Preparedness, Response, Recovery,...

Hurricane Katrina Case Study On August 29, 2009, Hurricane Katrina struck the United States Gulf Coast. It was a Category 3 Hurricane, according to the Saffir Simpson Scale. Winds gusted to up to 140 miles per hour, and the hurricane was almost 400 miles wide . The storm itself did a tremendous amount of damage, but the storm’s aftermath was cataclysmic. Many claimed that the federal government was slow to meet the needs of the hundreds of thousands of people affected by the storm. This paper will examine the four elements of disaster management – preparedness, response, recovery, and mitigation – as well as an analysis on the data presented. Before we discuss disaster management, it is important to briefly sum up the events of the events that began on August 25, 2005 to fully understand the brevity of the situation. Meteorologists began warning inhabitants of the regions that were hit by Katrina on August 23, 2005. By the 28th, evacuations were under way, that day, the National Weather Service predicted that after the storm hit, â€Å"most of the [Gulf Coast] area will be uninhabitable for weeks†¦perhaps longer.† (Spowart, 2015) New Orleans was particularly vulnerable. More than half of the city was built below sea level, and the levees protecting it were built on porous sand. The poorest parts of the city were completely unprepared for a storm surge. Many of these citizens lacked transportation and could not evacuate, and were left to wait out Katrina in theirShow MoreRelatedEssay on Phases of Emergency Management915 Words   |  4 PagesEmergency Management Emergency management is often described in terms of â€Å"phases,† using terms such as mitigate, prepare, respond and recover.

My So-Called Enemy Short Film Review free essay sample

The world is formed by connections, both positive and negative ones. A relationship is the manner by which at least two ideas, protests, or individuals are associated, or the condition of being associated. Connections come in numerous appearances, for example, family enrollments, fellowships, insinuate connections, on a bigger scale, common undertakings, and some more. Likewise, interests are a tremendous segment to connections; an ordinarily known intrigue as well as debatable subject is religion. Religion has united individuals since the very beginning. One situation, which incorporates a tie amongst religion and relations, is the short film, My So-Called Enemy, which gets in contact with the connection between the Jews and Muslims in Israel and Palestine. In this short film, the connection between six young ladies from restricting nations (Israel and Palestine) is endeavoring to discover peace in their home of warfare. After watching, watchers may make sense of that individuals who are instructed to be each other’s enemies can look past the awful and move toward becoming companions. We will write a custom essay sample on My So-Called Enemy: Short Film Review or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For instance, one of the Palestinian young ladies, Inas cites, When I see the Jewish girls as individuals, I love them and all of them are my friends†¦we talk every day, and we eat together, we dance together, and we see them always together. But when I remember that they are Jews, I have my feelings at the same time†¦because their people killed my father. This shows that we’re taught at a very young age what to think about a group at a young age, yet we can think about them differently when were thinking about them individually. When there’s a Jerusalem explosion that kills seven, a Palestinian Israeli girl, Riyam says, â€Å"I did not go put that bomb there, they are blaming us indirectly, they’re blaming.. cause all they ever do is just victimize themselves.† Showing that she knows that people blame groups indirectly just as they were blaming the Palestinians. Another huge piece from the video is the point at which the six young ladies are in a circle hopping around together, yelling, Sisters! Sisters! Demonstrating the young ladies hopping in delight together showing how they genuinely found their tranquility and satisfaction, now withstanding their political and religious contrasts.
