Erich Friedman complains that he can't post to math-fun, and asks me to forward this. This seems to almost put the problem to rest. Rich, can you troubleshoot to see what Erich's posting trouble is? He's a valuable funster. ---------- Forwarded message ---------- From: Erich Friedman <efriedma@stetson.edu> Date: Fri, Aug 30, 2013 at 1:01 PM Subject: Re: [math-fun] Calculus of variations problem: the one-wire cage. To: Allan Wechsler <acwacw@gmail.com> in 1946, p.a.p. moran showed that as long as the curve contains no 4 coplanar points, a reasonable assumption, that the maximum volume is achieved by one turn of a circular helix of height 1/sqrt(3) and radius 1/pi sqrt(6). unfortunately, i can't post to math-fun, so please do so for me. erich friedman On 8/30/13 12:02 PM, "Allan Wechsler" <acwacw@gmail.com> wrote:
