Re: A Simple Mechanical Calculator for Sine
Equation of track: radius(θ) = a+1 + sin(θ) "a" is the distance from the pivot to the "dimple" in the curve. Attached figure "eqn.png" shows track curve for a=0.2 If you make "a" larger, say a=1, you can get a track with virtually no dimple (it may slide a bit smoother). See figure "no dimple.png" Last edited by Ether : 27-12-2011 at 13:54.
