Ridgeline Physics

[chickenwing]

It's all magic. It really has nothing to do with physics or algebra or anything else based in reality as far as I am concerned it just works and that's how I like it.

I was looking at doing the same, been posting about it on BCUK

First my Idea...

With the blue whoopies I can adjust ground clearance, head height and foot height (compensating with the red whoopie)
With the green whoopies I can choose where between the trees I want to be situated (avoiding a puddle, clump of thistles etc. Theoretically I don't need to be in the centre with a SRL)
With the red whoopie I can adjust the hang of the hammock (using the green & blue whoopies to compensate)

then came the controversy...

Not sure the short adjustable lengths attached to the ends of the hammocks but before the ridgeline are needed. Surely with the minimum bury length required for the whoopieslings must make the minimum tree distance larger, and mean you have to place your straps higher to achieve the same angles a shorter oal hammock.

I'm with HB on the small whoopies, I think you've found a solution for a problem that doesn't really exist.

I appreciate what your trying to achieve, but looks too complicated to me

Getting the whoopies extra tight was an issue and I ditched the soft shackles in favour of Maillons as I like being able to add stuff to em whilst under tension.

montainm, I think you are opening up a lot of variability into your hang. Everytime you adjust your blue whoopies, you will need to correspondingly adjust your red whoopies to maintain the same hang angles in your hammock itself. I think you will basically be re-dialing in the hammock every time you hang it.

Also, based on your picture, trying to keep your suspension and ridgeline basically flat like you have it is going to exert a tremendous force on the suspension and trees.

Aye - but once I've got my desired lengths dialled in and I'm comfy then I'll lock both blues and the reds in place with a simple knot on the tail of each whoopie - most of the time this will never change - but it does give me options if I need to.

I've been advised on the horizontal load so I'm going to hang the tree huggers a bit higher next time. But I'm also going to pop my fishing scales in there to get a true measure as when tested it seemed to take it in it's stride.

How does the ridgeline work? (A free body diagram would be helpful.)

Sorry for the late post, but my Ridgeline works GREAT and I've even attached a diagram so you can see it. Not sure about the physics behind it. It just works!



Oh wait. Wrong type of Ridgeline! My bad...

Yes! Magic = good, physics = bad. Though I must admit, I kind of enjoyed slogging through Grizz's writeup...reminds me why I steered myself away from the world of engineering!

Based on the weight and angles, you could easily be 1000+ lbs. of force. I would hate to see you tear up your scale.

But, if you have fish scales that hold this kind of weight, I definitely would like to go fishing with you!

Great photo, but hope your head is hanging uphill, or your gonna get a skull knockin headache the way your Ridgeline is inclined!
