Nah - it's like popcorn, just overheated.:D :rolleyes:

bbtourer - do you pull the suspension tight when you hang or do you hang loose with a lot of sag in the suspension - even before getting in the hammock - as pictured by hitchman?

I finally measured the angles on my hammock with the two ridge lines. My "eyeball" estimates were off by a factor of at least 2.

angle beta for the long ridge line: 29.8 deg (less sag)
angle beta...

ahhhh -

bc = horizontal force due to person sitting in hammock

ac = horizontal force due to person sitting in hammock + horizontal force due to tension in structural ridge line

ac - bc =...

Gee - you make it seem so easy - all I did was subtract the horizontal forces.:D

Your solution is better for the Freshman textbook though. :rolleyes:

hitchcraft - browse through this thread. It discusses how tight people pull their HH when hanging - it's been awhile since I last read it, but if I remember correctly, the consensus seemed to be that...

Ahem - "discussing" please :rolleyes: :D

Okay - I've been able to think about this over dinner time. What else do you think about??

hitchcraft and BB351 are right. The force D in my previous post is indeed the weight of the occupant ....

Okay - I have thought about this and drawn some diagrams.

Lets look at diagram 1:

This is the classical formula. The force...

I'm understanding you completely - I don't think the reverse is true. You seem to want to totally deny that the ridge line has any effect. I think you are wrong. I don't think we can agree coming...

Trying to analyze the forces on the hammock based on the rope strengths is not a very good method for engineering.

Yes, you can replace the hammock by a blackbox, but when you do so, you have to ascribe to the blackbox the properties of the hammock. Assigning zero properties to the ridgeline and saying that the...

Ignoring the ridgeline is by far the easiest way to go but unfortunately leads to incorrect conclusions.

In one thread someone asked the members of the forum how they hung with the structural...

Okay, you now have the original force applied in pulling the rope/line/cord tight, plus the weight applied as indicated, plus the elastic force exerted by the fibers in the rope/line/cord used when...

Well - yes and no. The ridgeline doesn't create the extra force, the extra force is created when the ridgeline is pulled tight.

JJ - that is true only for a hammock without a ridgeline or for those with a ridgeline which isn't pulled tight when hung. For those with a ridgeline that people pull tight, that formula still...

Agreed, but he's said he's using a Hennessy, and the Hitchcraft site depicts a Hennessy being hung. Also, I believe that Hammock Engineer uses a structural ridgeline. Thus, I still do not think he is...

hitchman - I think you are overlooking the horizontal forces. So far you have considered only the vertical force, the weight, and seem to feel that the horizontal forces are not worth mentioning. But...
