Given an arc, find the radius. Accidentally deleted the part where the smaller perpendicular bisectors extend through the center of the circle. Where they meet is the center of the circle.
I'm going to witness some steel plate at a tank fab shop to determine if reqd radius achieved on plate bends. Easiest field verification method using a tape measure and chalk line?
I have to field measure a half circle in order to find the unknown radius. I have an idea of how to do it. I plan on using a straight edge ( piece of conduit) , then measuring the height of the arc, then using the Pythagorean theorem to find chord of half the arc. I was hoping your video would have gone over this formula in some way.
@@Wjracer106 In the last one, mulitply a * a (10*10=100), divide 100 by the height h (100/4=25), this gives you x, add x + h (25 + 4 =29), this is your diameter, radius 29/2=14,5mm.
Half the chord squared divided by height plus height = d divided by 2 equals striking point in my line of work aka the radius.
Nice one!

I'm a piping guy not a tank inspector. Quick field tips please
@@DSchafer I use tape measure and pencil or sharpie.
@@DSchafer When I ordered bent material, templates were often the most practical. If high precision was needed, we sent dxf files to the laser cutter.
I came here HOPING to substantiate what I had read in a book . After watching ur video I’m more confused.
Let me know what your looking for. I'll clarify it for you if I can

@@CONSTRUCTIONOMETRY-hj7jt I wish I could upload an image.
Send the formula. I can probably explain how it is derived geometrically.
@@CONSTRUCTIONOMETRY-hj7jt send it where, when I’m responding to you , I don’t have access my photos!!
I cannot for the life of me figure out the last formula. Get it wildly wrong everytime i try
Pay close attention to the parenthesis, then I I think you'll get it. If you are still having trouble you can look up PEMDAS order of operations.
@@CONSTRUCTIONOMETRY-hj7jt you may as well ha e typed that in Japanese

bro!!!!!!!!! any carpenter can do that without all those
chicken guts
Hahahaha
Huh?
