Endpoints-of-rope-parts-directionality-linears-part2-180arcs-are-not-just-2-90arcs more endpoint trace of directionality thru rope from input to receiving endpoint on 180 arc, and how that is just not simply 2x 90degree arcs, for this is where the compound force of 2/1 pulley and best Nip position come from.  This is for external linear force feed thru Standing Part into controlling arcs of hitch termination or Bend coupling type node deformities in otherwise straight linear line of (rope) force.
