How Steel Chemistry Affects Steel Properties

How Steel Chemistry Affects Steel PropertiesSteel chemistry is the science of creating iron from other compounds, whether it's iron ore to steel, or coal. The chemistry of steel is quite complex and while it's a known fact that iron and steel are the most common elements in the earths crust, the science behind how they form is less well known.Steel begins its existence as either ferric oxide (FeO) or manganese dioxide (MnO2). These compounds are referred to as ferric or manganese and oxide respectively. But the amount of these two minerals determines what metals will form in the first place.For example, if the amount of manganese is too high, then it's going to result in iron and is going to be a very weak alloy. Conversely, if the amount of manganese is too low, then the alloy will result in a poor quality iron. This is why manganese plays such an important role in creating steel. It makes the alloy stronger and prevents the iron from turning to iron oxide.If the manganese oxide is a lot greater than the amount of ferric oxide, then the alloy will result in a very low grade iron. While this may not sound like a lot of change, it will make a huge difference in the strength of the metal that will result from the alloy.So, this is a good thing, but how does the composition of the steel affect its strength? Well, there are several ways that the composition of the metal affects the strength of the steel.First, the composition of the steel structure will determine its durability. Good grades of steel are more resistant to cracking and fatigue damage, which is why a piece of metal called AISI or Aramid is used to make precision equipment. These grades are also better at resisting and stopping penetration, the most common cause of fatigue and premature failure.The second way that the composition of the steel affects the strength of the steel is by acting as a dampener on the expansion and contraction of the metal. A proper amount of moisture has been shown to help kee p the material under tension and keep it from tearing when under pressure. This helps keep the metal stiff and increase the wear and tear of the material over time.And finally, the ability of the steel material to conduct heat is also directly related to its strength. Heat increases the rate of chemical change, which increases the rate of crystallization, and thus causes an increase in the rate of weight change. This again is why manganese is used in order to enhance the strength of the steel by increasing the metal's ability to resist heat.

Want to Learn Spanish Our Guide to Getting Started

Want to Learn Spanish Our Guide to Getting Started Suzy S. Learning a new language, such as Spanish, can be an exciting undertaking! Even if you are not planning to visit a foreign country on your next vacation, a second language can help keep your mind stimulated. Heres an overview of the different ways to learn Spanish, to help you determine which option will work best for you. Your Local Community College Remember that campus thats just down the road? You dont have to be a recent high school graduate to enroll or take classes there. In fact, many of the students at community colleges are in satisfying full-time careers and are just looking to expand their knowledge in areas that dont pertain to work. Check out the website, or even stop by their admissions office. There should be plenty of information for you about continuing education, including Spanish classes. Youll be looking at a minimal time commitment per week, and will be able to converse with the instructor and your fellow students. Of course, this only works if your personal schedule fits with the class time, and if you miss a class there is limited flexibility aside from working on your own to catch up to the rest of the group. Reading Books Most  libraries have a large assortment of language books. You can learn Spanish at your own pace this way, and you cant beat the price! In addition to language resource books, you might also be able to find short stories or novels written in other languages. This can help you progress, as long as you know which books are at the appropriate level for you. The downside to reading books is that you wont pick up any pronunciation tactics. Unless you already have a general understanding of Spanish before starting, you will probably run into issues with more complicated words. Many books that help you learn Spanish include pronunciation guides, but when youre moving up to reading fiction works, not all of the words will be familiar to you already, which can pose a problem. Using Online Resources If getting to your local library doesnt fit within your schedule, you can also opt for the online route. There are many free  resources available, including apps, blogs, videos, and online games. Similar to reading books in Spanish, however, this option leaves out the all-important aspect of conversing with fellow Spanish speakers to build your skills. Take a Trip to a Spanish-Speaking Country Even though you might not be trying to learn Spanish to head to a Spanish-speaking country, it is a great way to learn it! Most people you run into will speak mostly (if not only) Spanish, so theyll be glad to speak to you in their native tongue. After you learn the basics of Spanish, total immersion in the language can help you figure out the many nuances. However, this tactic can be frustrating at times if you dont have a good foundation in Spanish and are speaking with people who have limited English skills. Working With a Private Tutor If you can find a Spanish tutor in your area, or even online, this is the most flexible route available. Since a private tutor works with you one-on-one, he or she will cater the lessons to both your learning style and your pace not so fast that youre not mastering topics, but not so slow that youre getting bored with the lessons either. Your private tutor can also help you find online resources or print materials to help you between lessons. You can also ask your private tutor about traveling out of the country and learning Spanish on foreign soil. Many of our TakeLessons tutors have traveled extensively, and have many stories to share! So what are you waiting for? Get started learning Spanish today! Bonus:   Learn about the budget-friendly options for learning Spanish! Interested in Private Lessons?

What is it Like to Attend the University of Edinburgh

What is it Like to Attend the University of Edinburgh Aura earned her bachelors degree in classics from the University of Edinburgh. She specializes in Latin tutoring, Greek tutoring, and a number of other subjects. Below, she shares her experience at the University of Edinburgh: Describe the campus setting and transportation options. Aura: The University of Edinburgh is very urban. It has campus locations all over the Old Town of Edinburgh, Scotland. The School of History, Classics, and Archaeology, where I spent all of my time, is right in Teviot Place, near the main library. There are plenty of local buses to take you all over the city. Edinburgh is a relatively small city, so its totally manageable by foot or bicycle. All of the university buildings in the George Square/Teviot Place area are well lit and have security guards. I felt safe walking around at any time of the day or evening. How available are the professors, academic advisers, and teaching assistants? Aura: All of the professors have office hours and most are happy to answer whatever questions you send over email as well. The teaching assistants and tutors were extremely helpful, too. I was especially well-supported when working on my dissertation. My supervisor and all of the professors in my department were there for me to bounce ideas off of, recommend titles, and help me meet my deadlines. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Aura: Most freshmen live in the university housing. The buildings are large, so you meet a lot of people quickly. The food isnt great, but most of the buildings are new and the area is right near the park around Arthurs Seat. Its also quite central, about a 20 minute walk away from most university locations. After freshman year, people share apartments with friends all over the city. There are a lot of reasonably priced student flats. Which majors/programs are best represented and supported? Aura: The University of Edinburghhas all the typical undergraduate liberal arts majors, as well as veterinary, law, and medical schools. In a university of 18,000 students, I really appreciated how small my department was. I knew my Latin and Greek professors well and was friendly with all of my peers. I did have larger lectures when I took ancient history classes, but nothing staggering. The library was well-stocked for whatever I needed to research, and my professors were all major players in their fields. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Aura: Its always jarring being new at a large school, but the school organizes a great orientation week where youre out meeting new people and familiarizing yourself with the city. I found my two main groups of friends from my classes and from my field and ice hockey teams. The university has a huge number of clubs and societies, and joining them is a fast and fun way to meet likeminded friends. How helpful is the Career Centerand other student support services? Aura: The career center was pretty helpful when I was putting together my resume. It was easy to get an appointment to ask for some advice. Edinburgh has a good reputation within the UK and abroad, and large companies did recruit directly from the school. I ended up applying to grad school and my professors were extremely helpful with that process. How are the various study areas such aslibraries, the student union, and dorm lounges? Aura: There are a lot of students at Edinburgh, but there are a lot of venues, so most of the time places felt busy, but not overwhelmingly so. The student union had plenty of seating and cafes. In regards to the library, unless it was exam time, if you got there before 9:00 AM, you would have no trouble finding a desk. The gym could get busy, but if you timed it right, you never had to wait for a machine. Describe the surrounding town. Aura: Edinburgh is a gorgeous city, and because there is no area that is strictly Edinburgh campus, you are always wandering around in it. It is delightful being a tourist in your city, checking out the castle, cathedral, palace, and various museums and restaurants (most of which have some sort of student deal). The area near George Square is full of student-friendly cafes and shops. Students walk downtown frequently for shopping, cinemas, and more nightlife. Its easy to get to the train station to explore more of Scotland and there are numerous ways to get to the airport (its about 25 minutes outside the city center) to go further afield. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Aura: The entire student body is about 18,000 people, but this figure is spread out over many, many departments. I would estimate the largest lectures could easily have around one hundred people. However, whatever your major, you have more choice in classes in your third and fourth years of study, and so classes become much smaller at the honors level. In my first and second year I was in some very large history classes. In addition to the lectures in those classes, we always broke down into smaller groups for tutorials, which had 10 or fewer people in them. In my third and fourth year, I was never in class with more than 25 people. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Aura: I really enjoyed all of my classes and professors, but if I had to pick one, I would have to say that in my third year, I was in an Iliad class with Dr. Maciver, which was awesome. Everyone who does Greek is familiar with, or has probably translated, a decent chunk of Homer. However, the depth and the breadth of Dr. Macivers knowledge of epic poetry was inspiring. He created an environment in which it was not uncommon for students to laugh, feel sorrow at sad moments, ask questions, and have their minds blown by analysis of complicated Homeric similes. It was interesting having Dr. Maciver as a professor for the Aeneid, a Latin epic which borrows heavily from Homer, the following year. Check out Auras tutoring profile.

An English physicist, philosopher, astronomer, and mathematician, Isaac Newton was born in 1642 in Woolsthorpe, Lincolnshire in the UK.His father died several months before his death and, consequently, Newton’s mother remarried when he was three years old. It was his maternal grandmother and his stepfather that looked over his up-bringing.The physicist grew up in Woolsthorpe ManorNewton was a very curious kid, observing the functioning of the machines around him. As a student, Newton was a bit scattered and always had his head in the clouds. Even still, he taught himself how to fabricate sundials, wind turbines, mechanical transport devices, kites, etc.Some years later, his mother took him out of school with the goal of making him into a farmer even though, at his fourteen years of age, the future mathematician didn’t show any interest in that domain. His success can be traced to an old professor who managed to convince his mother to let him prepare Newton to enter the University of Cambridge.It was there that he became, in 1661, a student of Trinity College of Cambridge. To avoid paying school fees, Newton performed domestic tasks for the school. This arrangement permitted him to study arithmetic, geometry, trigonometry, astronomy and optics. Isaac Barrow, the great mathematician and professor of Cambridge, took Newton under his wing. Newton eventually received his diploma in 1665.After his graduation, the scientist spent his time elaborating several hypotheses and laws on universal gravitation and on the movement of bodies. He studied his environment and how the objects around him moved. He made great discoveries by studying the behaviour of light and the function of optics. During his career, on of Newton’s most celebrated inventions was the mirrored telescope.But Newton didn’t stop there. The accomplished scientist also searched to elaborate his reflections on theology, chronology, alchemy and chemistry.After a great career as a scientist, Newton distanced himself from the English capital to reside in Kensington, where he died in 1727. He was the first scientist to be buried in the Westminster Abbey.Isaac Newton and his W ork on GravitationNewton is known, before everything else, for his research on gravitation. According to legend, Newton sought to understand how the moon could rest in orbit around the earth. He observed and noted that, along an orchard, apples always fell. He discovered in that moment the force of attraction under which the apple had been subjected to and developed the law of gravity. He estimated that the reason the reason for the fall of the apple was the same as the reason why the moon rested close to the earth, despite the distance.To verify his hypothesis, Newton put in place an equation according to which the force of gravity depends on the inverse square of the distance between two objects. We call this law the law of the inverse square.To develop this, the scientist expanded his hypothesis to encompass stars like the sun, and other planets as well. However, Newton didn’t make any calculations on the relationship between the apple and the tree because the distance appeared to him too short in comparison with the stars and planets in the sky.Nevertheless he is principally known for his research in gravity. Even today, the legend of the falling apple forms a part of history that we love to tell in science and mathematics courses.Discoveries are often made in the most unexpected places: Newton's was under an apple tree!

Taken under the wing of Isaac Barrow during his studies at Trinity College of Cambridge, Newton confided with him a manuscript in which we wrote several different mathematical conclusions.Named “On Analysis by Infinite Series,” Newton described and developed integral and differential calculus. Newton called this the method of fluxions.Integral and differential calculus implied other mathematical calculations like:The percentage change of quantitiesThe inclination of curves on a given pointThe calculation of minimum and maximum values of functionsThe calculation of areas comprising of curvesOnce in the hands of Isaac Barrow, the maths professor showed the manuscript to many of Europe’s then great scientists. Newton became widely recognized as the founder of mathematical calculus and acquired a place amongst the greats of his time.Newton also made himself known for what we call now Newton’s binomial. This is defined by the formula “(a+b)n,” which holds true for any value of n.Legend has it that at the point of retirement, Isaac Barrow gave Trinity College of Cambridge the idea to hire Newton as the new professor of mathematics. Newton and the college unanimously accepted. The mathematician gave his first maths course in optics, one great passion that him and one of his predecessors, Euclid, shared.Newton's Work on the Behavior of LightAmongst all of his biggest researches, Newton payed particular attention to everything concerning optics. This passion began while the English scientist first took an interest in the behaviour of light.For scientists of the era, white light was considered as homogeneous and it was believed that it could not be distorted.Newton, like always, liked to and did challenge the certitudes of his time.To do this, he used a transparent prism and exposed it to the rays of the sun. During these experiments, he realized that the light of the sun transformed itself into many rays of light which were all different colours. He called this a “spectrum.”He introduced, from then, the term refrangibility, a phenomena that explains that the different colours in the rays of the sun, by the differences in the degrees of one property, can bend when in contact with certain objects. Objects whose material allows the light that enters it to change direction is called a “refracting object.”Make your learning maths a easy journey by getting good maths tutors here.Newton was also involved in setting the foundations for classical mechanicsEach colour that composes the rays of the sun possesses a different refrangibility. During contact with a prism, all of the colours of the spectrum don’t behave the same way. Newton studied them and took note of what he saw during these experiments.All of his observations left an enormous mark on the domain of optics, which Newto n continued to study for the rest of his life.If you're interested in some more interesting and foundational mathematics principles, check out ancient Greek philosopher and mathematician Thales.Newton's Famous Telescope ReflectorNewton’s discoveries concerning light and the phenomena of changing refrangibility greatly influenced the world of science. Newton took advantage of his role as a maths professor at Trinity College of Cambridge to continue to study the field of optics.After having discovered the behaviour of spectrum of light and the different colours that came out of the face of a prism, Newton revisited the function of telescopes which were made at the time using lenses.These lenses were fabricated using one material, glass, that modified the trajectory of beams of light. Newton decided to replace these lenses by mirrors with the idea that the colours could reflect from mirrors the same manner but more efficiently. It was in 1668 that Newton was ready to fabricate his mo dified telescope.The telescope was made with a mirror of 3.3 cm and a magnification factor of about 40. The gifted scientist combined in this invention his love for mechanical objects with his obsession over the function of objects and light.Some years after his invention, Newton acquired letters of nobility from the Royal Society, the association of accomplished mathematicians, to test his telescope and to create a patent for the machine. His status as a veritable genius in the sciences and maths was finally validated in the eyes of both his generation and for the years to come.If you're interested in learning more about the famous mathematicians in history, check out this guide!
