Thank you so much! I've been banging my head against a wall for 3 days trying to figure this out on my own. Got kinda close, actually. But man, I'm not sure I ever would have resolved it, though. Thank you!
This is the Best youtube channel ever to Engineering Drawing !! Thank you so much... Your each and every video help me to do all of my University Assignments... Cheers to Arthur Geometry !! ;-)
Please help me to understand this😭 Draw an arc tangent to two unequal circles. Given two circles of unequal radii and the Radius r. R1= 15 mm R2= 25 mm R = 20 mm(👈this is the thing that i mean) Just really what is R = 20 mm for😭
If R is the inner radius between R1 & R2 then add R1 to R, add R2 to R. With that radius draw an arc from the centres of R1 & R2 respectively. Where both arcs intersect is the centre point for R. For external radius, subtract not add then do the same.
Thanks so much for this. I needed to know the surface area of a TO-3 transistor for thermal calculations. With your video, I was able to draw it in a CAD program and query it's surface area. en.wikipedia.org/wiki/TO-3
