      HI Theresa: Thanks so much for the positive feedback. My idea is to make straightforward, simple and easy to understand videos. No nonsense. Your comments validate my goals!

    What he didn’t explain here is that if you have a calculator with sine and cosine on it you don’t have to remember any constants. For travel of advance you want secant of angle which 1/sin of angle Ex. 1/(sin of 22.5) = 2.613. For travel of offset you want cosecant of angle which is 1/cos of angle Ex. 1/(cos of 22.5) = 1.082. This works for any degree offset like for a 45 degree offset your advance and offset will be the same so you can use secant or cosecant therefore 1/(sin 45) or 1/(cos 45) will both = 1.414. Have the travel and want the advance or offset? Well it’s sin of angle or cos of angle. Sin 45 = .707 1.414 is the square root of 2. Remember a^2 + b^2 = c^2 for right angle triangle, so if you use a unit circle where radius =1 (I know you’re asking what does a circle have to do with a right triangle? Just trust me) you’ll have 1^2 + 1^2 = c^2 therefore 1 + 1 = sq root of 2. Sq root of 2 = 1.414. It’s all trigonometry revolving around the unit circle. hope this helps someone because i just finally made sense of this while studying for city plumbers. They should’ve shown us in high school what these things were used for them maybe I would’ve paid attention in trig class anyway no point memorizing constants when you can calculate for any angle.

    A little tip for your viewers, at the end of your video measurement was 14.18 inches. The .18 represents 3/16 For every .06 = 1/16. 16x.06 =96 or 1 inch hope this helps. Retired Steamfitter

    thanks, gotta run a little 4" pvc sanitary pipe with an offset tomorrow. i totally get the offset x 2.61 = travel.
    i just don't see where you use the other formula. you have an offset and fittings.

    • @tradestutor1191
      @tradestutor1191  3 года назад +4

      Hello: I'm assuming you are talking about the "advance X 1.08 = travel? That's essentially a trigonometry number when dealing with 22 1/2 degree offsets. You could use that portion of the formula to find how far of an advance you needed to go. By the sounds of it I don't think that part of the formula will be needed for what you are doing. Note: Don't forget to include fitting allowance when calculating the travel. This video does not take fitting allowance into account. I make another video for that calculation. Take care and thanks for watching

    If the two 22.5° offsets make a 45° left/right (rather than parallel), does this approach still suffice?

    How do we know that the constant # we need to use for this degree is 2.61?woud you pls explain and teach us what we are going to use constant number in different kinds of degrees..

    • @tradestutor1191
      @tradestutor1191  3 года назад +1

      Hello Lucky: The constant 2,61 is actually a trigonometry number. If you were to apply trigonometry to this situation you would end up using the 2.61 in your equation. For other angles you could use your trigonometry formulas (SOH CAH TOA) to get the constants you need to use.

    Good day, i got lost a bit heheheh why in 45 degrees. offset and advance are same multiple and division by 1.414 but in 22 1/2 offset and advance are different where to multiple Please correct me if I'm wrong. Thank for

    • @tradestutor1191
      @tradestutor1191  5 лет назад

      Hi Eduardo: in 45 degree the offset and advance are the same due to the fact that in a right angled triangle both of the other angles are 45 degrees. This means that both are the same length and both use the same number (1.414) in the math. However, in a right triangle with a 22 1/2 degree angle the other angle is 67 1/2 degrees. This means that in order for you to find one side or the other you will need to use different multipliers. I hoped this helped.

      Hello dodging wave:
      Those numbers are trigonometry numbers. If you were to find the sine of 22.5 or the cosine of 22.5 or the tangent of 22.5 you would come up wth those numbers.I just skip the trigonometry part and just memorize the numbers and their relationship in the triangle.

    Why not use a 30 degree, if offset is 4” , i.e. , obstruction . X’s 2 = 8 . If 1st mark on conduit is 8” . Add 8” , 2 mark is at 16”. Bend pipe first mark to 30degrees. , flip pipe 180. Bend 2nd mark 30 degrees. Job done. We want to get paid , guiseppe. U think the boss want a trig. Major to bend pipe?
