Fewer posts on upper-level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Using standard load estimates from LVL span tables: 40 psf live, 15 psf dead = 55 lb/sqft. The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries.

And how did those numbers get so precise up to four decimals digits?.How did the author know that $3.982$ is the leading coefficient to use?.Why does this weird-looking equation pop out from nowhere?.These are basically pictures and animations created in Desmos primarily through the clever use of equations and inequalities - among other features such as tables, animating sliders and regression models. Indeed, if you go to this official staff pick page, you should see that a whole bunch of creative artworks were already being created - anything from cartoon characters, landscape to logos and portraits.īut here’s a problem: when you reach a Desmos artwork page, you get to see the end-result with all the equations and inequalities, without necessarily having any clue about how the sketching process comes about from the beginning to the end: He currently teaches at Horace Greeley High School in Chappaqua, NY and also at CUNY Lehman College in the Bronx, NY.If you’re of the type who enjoys playing around with graphing calculator, then you might be interested in the so-called Desmos Art. A passionate teacher who strongly believes that understanding mathematics can help all students develop critical thinking and problem-solving skills, he is also known for his use of different technologies to engage his students and bring math concepts to life.

I hope you find these ideas helpful and are able to try them with your students! I have included my instructions for their final project below. I honestly feel that by not giving a lot of (specific) instructions, students were empowered and had complete ownership over their projects. To my surprise, many students used 30+ equations and the quality of their work was truly amazing.Īs I mentioned before, I tried keeping the instructions somewhat loose because I did not want to limit my students. I asked for at least ten equations with different domain/range restrictions. I tried keeping the instructions very general because I really wanted them to have ownership over the project. Students completed different projects that went from school/team/club logos to an actual portrait of Horace Greeley. I decided to center the project around school spirit at Horace Greeley High School in Chappaqua, NY. Our first project took place after we covered polynomial and rational functions. They had so much fun with it that we actually had three art projects during the school year. One very successful assignment my precalculus students really enjoyed was their Desmos Art Project. With that in mind, one of my goals was to provide my students with activities that truly fostered authentic work. With our current technology, students have access to step-by-step solutions at their fingertips to almost any problem we give them. ![]() ![]() This past school year, as many other teachers, I taught in a hybrid model with some students in person and some others at home. Working as a math educator for the past twelve years has taught me that an effective way to engage students is by giving them choice in how they demonstrate mastery of their learning. ![]() ![]() I knew a blacksmith that used an anvil built by lamination of plates arc welded together. They had anvils cast (probably in ductile iron) and hard faced using special welding rod (Eutectic(tm) most likely). At Colonial Williamsburg they wanted anvils with an old look but did not want to be wearing out real antiques. Otto Schmirler's personal anvils mentioned above were made of cast steel from his own patterns in several sizes. Other specialty anvils include the ancient Nailers anvil, Sawyers anvils, Armorer's anvils, Jewelers anvils and various stake anvils.ĬUSTOM ANVILS: Surprisingly custom made anvils are more common than you would think. This Eastern way of working was practiced in Ancient Greece and is still practiced in India and Southeast Asia. THEN, if we wish to avoid being Eurocentric in our views, the classic Japanese anvil was a rectangular block set into the ground the smith also sitting on the ground. Europeans are also keen on double horned anvils (one conical, one pyramidal). Currently European anvils are big on an added block on one side of the anvil extending to the base called an upsetting block. Formerly, Hay-Budden produced a Farriers anvil that was their standard anvil with one corner of the table removed and two pritchel holes (one extra). Today's American made Farriers Anvil has a very narrow waist (approx equal to the face width) and exaggerated horn and heal. V-grooves ground in the face are also offered. Specialty anvils such as the Farriers anvil sometimes have a bulge to one side of the horn for forging caulks. It includes "Acme" (probably Hay-Buden) steel faced wrought iron anvils, "Steel Face Cast Anvils" and "Chilled Face Cast Iron Anvils." Weights range from 220 pounds to 20 pounds. ![]() In 1985 the same catalog was reprinted a second time in cooperation with A.B.A.N.A. In 1984 the Mid-West Tool Collectors reprinted the 1915 Sears, Roebuck and Co., Tools Machinery Blacksmith's Supplies catalogue. Reprints of catalogs such as old Sears and Roebucks are also a good source of anvil data. This catalog also included a variety Blacksmith's hand tools and forges. "The face is made from one piece of high grade tool steel, accurately ground and tempered. Industrial Supply Corp., Richmond, VA, 1955 catalog, page 172 lists Fisher "Eagle" Anvils from 50 to 700 pounds, Old industrial catalogs will often include photos and specs of the anvils they carried. ![]() The most beautifully illustrated book about Blacksmithing that I've ever seen. Then try Eric Sloane's A Museum of Early American Tools, pp.90-93 Early, Colonial, Stake, Nailers.Īnd for a classic of custom design see Otto Schmirler's Start with Bealer's classic The Art of Blacksmithing, p.65 Medieval Anvils, p.66 The London Anvil and nomenclature, p.68 A Liêges anvil. Today there are still a number of manufactures making anvils but in small quantities and there are still organizations and individuals that make anvils to suit themselves.Īny book on blacksmithing will give the shape and basic nomenclature. Other than this brief period anvils were made in a great variety. Most anvils were made in the London pattern or it's modification the American pattern (narrower waist, mass moved into horn and heal). First, one should recognize there is no "standard" anvil.ĭuring the early part of the twentieth century, shortly before the automobile and other technical advances put the American Blacksmith out of business, anvils were made in great quantity and under great competition. ![]() ![]()
![]() ![]() It also allows for the combining of inch and metric taps and drills where convenient to do so. The drill size chart contains twist drill data for up to 1.0 inches in diameter. TAP SIZE CUTTING TAPS TRU-FLO FORMING TAPS INCH METRIC DRILL SIZE DECIMAL EQUIVALENT DRILL SIZE DECIMAL EQUIVALENT 0-80 3/64. Tap drill charts employ different measurement systems, including metric, wire gauge number, fractional, and letter. In both ISO and UN thread series, having a range of useful drill sizes allows designers and machinists to tailor effective thread depth for long holes, various materials and thread strength requirements. Tap Drill Chart Drill sizes given are the ‘closest’ drill size. A tap drill chart is a machinist’s must-have reference document that contains drill bit sizes, tap sizes, and their equivalent thread specifications that guide an engineer in fabricating threads and drill holes. Metric tap drill charts have the same drill size problem in that they use the same formula as that employed for the obsolete AS threads. Metric threads of the International Standards Organization (ISO) have the same 60-degree thread form as UN threads, though the diameters and pitches are not interchangeable. ![]() For example a 100% thread specification is only 5% stronger than a 75% thread specification but requires 3 times the torque to produce. Thread strength is not directly proportional to percent of thread. In general, tap tool life can be increased significantly by using a lower percent of thread and we suggest using values between 60% and 70% for most applications. Most tap drill charts call out only one tap drill size, and that will produce an approximate 75 percent thread. One very important factor is the drill size used to produce the hole that will be tapped. It’s just like selecting drill bit sizes for regular drilling, except that tap drill sizes are assigned to match industry standard sized holes for tapping (see more about bolt sizes and charts here). Many variables affect the performance of threaded holes and the taps used to generate them. So what the chart shows you here is the proper tap drill size that you can use to match the bolt or screw you’re cutting threads for. For example, I found 17/64 as the closest bit in relation to the 5/16″-18 (DH=.2583) tap because, when divided, 17/64 is only a couple of thousands away.Percentage of Thread and Tap Drill Selection: Using the recommended drill size is crucial to ensure proper thread formation. This size allows for proper clearance and thread engagement when tapping a hole for a 10-32 bolt. ![]() You can find the relative drill bit size with some simple math as well. According to the chart, the appropriate drill size for a 10-32 tap is a 21 drill. In this case, the most relative drill bit size corresponding to the 5/16″-18 tap is 17/64, which corresponds to an F drill bit. ![]() 2583, which you then round up to the nearest drill bit size. Insert the numbers for the 5/16″-18 tap into the equation to look something like this: Let’s use the 5/16″-18 tap, for instance. The other variable, Ni, is the other part of the tap.The full thread percentage depends on what size thread you want, typically between 70 and 85, but I’ll use 75 for this example.The DMB is the diameter measurement you figured out above.This formula looks a bit complicated, but don’t worry. Once you have the diameter, you can insert it into the formula DH=DMB -.0130(% of full thread desired/Ni). What is Tap drill Size Tap Dill Size is the drill diameter we should use before a tapping operation. You can physically measure the diameter or look to the first number in the tap’s specifications instead.įor instance, the diameter for both the 18 and 24 5/16″ taps is 5/16″ or. First, you need to get the diameter of the tap. To calculate your tap drill size, you need only a basic understanding of math and what size tap you’re using, which is the 5/16″ tap. ![]() ![]() ![]() With its headquarters in Dallas, Texas, Brinks Home Security employs over 1,200 people who install and monitor its highly responsive, smart home security solutions that protect more than one million people in the United States, Canada, and Puerto Rico.

![]() ![]() In Bohr’s atomic model, electrons are in a given orbit. Bohr’s atomic model is very close to the atomic model that can be seen these days. One hundred years ago, it was discovered by Rutherford that most of the atoms were empty.Īfter that, Niels Bohr presented a more refined atomic model. Positive charges within an atom are spread throughout the entire volume, and electrons were thought to oscillate around fixed points within a cation (muffin). The raisins on the outside of a muffin can be compared to the electron. However, real atoms can be divide into electrons and atomic nuclei, and using a particle accelerator can also divide atomic nuclei.Ībout 200 years ago, an atom was imagined to be like a muffin with raisins. ![]() When We didn’t know much about the atom, we thought it would be a solid lump like a billiard ball.
