BB and JJ--before we create the vertical tension on the rope, I break a sweat and pull on that rope as hard as I can, and fasten it. P lbs is what I can apply on a good day. So there is that much tension on the rope before climbing into the hammock. Now I climb in and create the additional stress whose formula we know. P did not go away. So is the total tension P + ASWFWK ? Does trigonometry come sneaking back here too?
BB--yeah, I can see that the stress on the ridgeline could have some interesting geometry.
