    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...

    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...

    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
