    Years ago I drew a plan for a client and learnt trigonometry. I'm not sure when I subscribed to you. This is the first time I seen other members of your family. The cheat book. So cute.When my daughter was young I took her with me to the tool place. As soon as I got there she wanted to leave. I'm not sure why trigonometry is not taught to apprentices when doing carpentry. Once you learn the formulas and the right teacher its not hard. My favourite is tangent. I recently learned another method using cos from another utube builder uploader. Trigonometry is not the only way of calculation as I believe there should be another method such as in the way the pyramids were built. Their level of expertise was better than what we have today. So we use a pie formula basically for trigonometry which calculates in squares. The more digits the more closer to accurate or finer tolerance you can achieve. Its still always within a square which is on an angle. That's opposed to a straight line. Anyhow here I go, get yourself a scientific calculator or use your phone. The trouble with phones you may need dry hands and often need to type the pass code to unlock your phone. Then find calculator. When you divide height by length save the result. Then press second function tan which is tan inverse. Then press the saved figure. This will give you the degree angle. Now if you divide the length into the degree and save the result. Press cos then result that will return the length of the angle cut. I hope that's not too confusing. I may and do another upload from my channel. Thanks for the upload.

    For me, the ideas in ua-cam.com/users/postUgkxAfqpMLyFn37qcqUl0FAzqkkycQeXqrhP Plans were a starting point for building different sheds . Ryan gives ideas that allow an individual to draw nicest conclusions into the design and building of his or her own shed.

    Thank you so much I had forgotten how to calculate common rafter length the real way no Framing square no cheat book and you refreshed my memory btw this is the best video Ive found after searching for a very long time on the subject ! 👏

    4:35... Exactly, as very few students have "applied learning" opportunities. Understanding Pythagorean Theorem (and the associated 3-4-5 triangle methodology), as well as understanding sine, cosine, and tangent usage can be very helpful to builders. However, if the practical application isn't taught, it is "knowledge" that will be neither applied nor remembered.

    Too bad we're teaching behind a computer screen these days. However, IF I was back in the classroom, I might have one of my classes break into groups, and do the computation for the Pythagorean Theorem on paper. After that, have them build what they figured out using rolled up newspaper as the rafters and see if it's symmetrical. Happy Easter to you and your family. Stay Safe!

      The decimal portion of the 28.84" hypotenuse is .84. So two ways: 1. Have a 16ths table (or use a calculator) and see where the number falls... 13/16 = 0.8125, whereas 7/8 (14/16) = 0.875. So he rounded up to 7/8 because .84 is greater than 13/16. 2. Multiply the decimal portion (.84) by 16 to find how many 16ths... 16 x 0.84 = 13.44 and use the whole part of the number, which is this case is 13, and through that over the 16 (to arrive at 13/16). But again, he rounded up since it was slightly more than 13. Technically, if taken out to 1/32" increments, the fraction would be closest to 27/32" (as 27/32 = 0.844), but rough framing isn't that precise. That's for certain finish work...

      If you convert an inch to 100’s,
      every 1/8 =12.5.for example one inch has 8-8ths ie 100/8=.12.5
      1/4=.25
      3-8=.3750
      1/2=.50

    You divide the SPAN by 2 to get the Run... In most cases.

    • @armychris9148
      @armychris9148 4 роки тому

      Span minus ridge divided by two equals the adjusted run !

    • @reddawgrup1779
      @reddawgrup1779 4 роки тому

      I never used the adjusted run. When cutting rafters you (I) get in the habit of laying out the rafter with the theoretical line length and the seat cut then I'd simply deduct one half the ridge thickness and draw my new plum cut line. Of course nowadays you just grab you rafter book look up the length and lay it out from there... No fun in it anymore.. Lol.

    I'm confused. You said the run was 24' but in your book, you point to a run of 2' .

    • @mrprecious1234
      @mrprecious1234 3 роки тому

      The run in this example is 4 feet (48") Using half of the run that would equate to 2 feet (24"). The roof pitch (angle) is an 8 inch (8") rise for every foot (12").
