I used to be a mechanical engineer
The stress on whipping is 50%.
Yes, it is pulling 100% along the axis of pull, and there is a lateral component of 50 (compression ) each sides (statically fixed, and still) and of 75 %along the throat line of Dyneema
, to close the triangle of forces.
Dyneema has two lines, each taking up half of 150% of nominal pull, on the increase due to the bending up to 150%
Same for the thread of whipping. They avoid the release of loops horizontally, therefore they match the 50% component of stress perpendicular to the pulling line.
Point is another one: first loop will absorb say 65% INITIALLY of the total nominal stress (50%) and will, though minimally, stretch and loosen, giving out some stress, going down to say (??) 50% of nominal stress.
Second closest loop will absorb say 30% of nominal stress, with trivial deformation, for our purposes.
Third pull carries up another 15%,.. 4th and 5th the residual 5%, assuming the 6th loop (at 1 diameter distance, better of 1,5X) unstressed.
That said, I knew of these rings being used for 3D regulation of clew-points...only... what ELSE??
Should I be concerned at having none on my cruiser?? :-)
