Graduate Finding the Radius of Curvature for a Helix: What is the Formula?
Hi Ok, I've found a website that has allowed me to find the solution I wanted. http://ca.geocities.com/web_sketches/calculators/baluster_radius/baluster_radius.html From the result given on that site for R, and using the fact that cos(pitch) can be found from the geometry given, it is...- DeltaT

Graduate Finding the Radius of Curvature for a Helix: What is the Formula?
Thanks, I don't mean to sound ungrateful, but I was particularly hoping to avoid using vectors, and was hoping for a solution using ordinary algebra and trigonometry. A previous poster, bobb513 appears to be saying he reached his result that way, where the angle involved is the slope of the...- DeltaT

Graduate Finding the Radius of Curvature for a Helix: What is the Formula?
I've seen that result quoted before in a textbook, unfortunately the derivation wasn't given, and so far it eludes me. Any chance you could provide a step by step explanation of how the R = r(cos)^2 result was obtained? DeltaT- DeltaT
