Dave! Saves me from:
>The shape of the cams on a typical camming device is given by the formula: r = eµř
>r is the radius, e is the natural logarithm base, µ is a coefficient which determines how >"fast" the spiral opens up (and it has more interesting significance, as seen later) ř is the >angle measured in radians….
I'll be forever grateful, will PM about sorting postage. |
