Thank you so much! From the baseline, you could drop the head end lower, or raise the foot end higher as both achieve the same result. I didnt ask you for your smart aleck input and do not appreciate it. So in this case, where the short vertical leg is Fv = half the weight, then the hypotenuse, T, is twice that, the full weight. Plug the numbers in and adjust the hang distance and hammock length and the suspension length will change or turn to zero, […] the hang calculator to determine the hang […]. The calculator takes the hang angle into account. Bye and sorry for the misunderstanding, The farther apart the two ropes get, the more horizonal force is required to produce that necessary upward force to hold up the hammock (half the weight). Also, although it is easy enough to bring out the calculator to get 83% of physical hammock length for a ridge line length, it would be nice to be able to specify physical length with a check box to use 83% – or just list on the page, 83% of 8ft, 9ft, 10ft, 11ft, 12ft for reference. This is why I encourage folks to hang their hammock at an angle. Thanks again. and tension on the suspension would greatly exceed body weight.

Learn most useful knots, for example from the Lesovik website. I tried the calculator considering my 4m hammock and a hang angle of 30 degrees (with zero suspension length). The math is a bit different for me as well (I had help making it work). Here is a link with some hammock examples, so you can see what I’m dealing with: http://www.denana.com.br/ I use Lash-it myself, and even smaller line. This distance prevents you from hitting the ground when you lay on it. Doesn’t show up for me either. Instead of a knot, you can also use hardware: carabineers, toggles, clips, etc. Again, if the weight is 100: 50 (50% of occupant weight) + 50 (horz. You can often squeeze or stretch a hammock into places the calculator say won’t work. If you get the chance, take a peek at it on The Ultimate Hang website here. Using the so called 83% rule, the hang angle will actually be 34°. What is the shortest stand I could possibly get that would work comfortably with my hammock? If nothing works, submit for a refund and send me any warning codes so I can tell the developer. Now we are dealing with the angles from the suspension height affecting the load that is occurring from the hammock now a fixed angle with the ridgeline. I just got a hammock and i don’t know a thing about them. or can you affect the hang with shorter suspension on one side? would it be functional? The wall also exerts force in the opposite direction in equal amounts. Packaged as a set of two, they are 3 in. A really taut hammock at 600lbs (5 degree angle) would exert a whopping 3442 lbs per strap!!!! Nice site by the way. I love the look of the Mayan Rada and am considering that with tree straps (which I am pretty confident will work on the brick columns (they are square, so will allow for easy wrapping).

Yes, but the hang height for bridge hammocks is much lower since the spreader bar raises the center of gravity AND the fabric of the hammock. i may not use exact numbers but pretty close, and it usually ends up falling too low to the ground or too tight to be able to lay down flat…., sometimes i feel like i may be choosing tree that are too close to each other, or there’s some other variable…i’m relatively new to this, but have hung maybe 8 times or so. – 3rd, adjust suspension length.

We don’t want to use the suspension straps, just the clips on the hammock when we hang them in our pergola. Each side is still sharing an equal amount of vertical force, but they will _increase_ the horizontal force, meaning each side could bear _more_ force than what is being held in the hammock. Anything from six inches to a foot is about all that’s necessary. However, the horizontal force is variable, depending on the takeoff angle of the suspension. I know, I know I’m looking for a developer. Also, one other question. Any suggestions?? A brand-new hammock may be shorter than its advertised length when it is first hung. I don’t believe it had the same tensile forces, but I’ll check in to it. If you are installing a single piece of hardware, such as an eyebolt, try to drill the hole in the center of the stud. Chain Hanging Kit. I would use a set of the ENO wall anchors and then use a short cord loop where you could connect your hammock. This is a great site.

As the horizontal component in one suspension cord has to remain the same as in the other (or the hammock will start moving) this also means the angle between the suspension cords and the horizontal plane will change. Hi Also, we understand that measuring tape is not a must-have on your camping or backpacking weekend - so a rough guess should be enough. My argument for the latter being correct: if the hammock and suspension were made of a material that would stretch until the hang angle approaches 90 degrees, then the suspension tension on each side would be half the weight divided by sin 90, regardless of what the hang angle was unweighted. No fields have been left blank. hopeing that you will make an android ver. My only concern was with the bolts going into the stud. 15 years, so far, so good. But there is also horizontal force, based on the angle of the hang. It shows a labeled image that displays all of the information you input so you can easily interpret the results.

If you hang two ropes, attach a sling (hammock) between the two, and add the weight to the sling, such that the pull is still directly up and down, then yes the weight should then be equally distributed between the two points/ropes. comments. Thank you for sharing and building on the real-world opportunities. I assume it is fixed, but without the HH here yet I don’t know. This is a great aid and it would be even better if we could fix the vertical height so the parameter we can change is the suspension distance from a fixed height to hammock ends. The calculator make it a lot easier for me plus learning a lot from your book, I have also made some of your DIY gear from the plans on the web site. I’d have to ask a builder. Your email address will not be published. Hopefully a universal app will be available for Android and iOS. It’s really a subjective measure based on your own preferences. It means the sit height isn’t ideal 100% of the time, but it is still usable. Distance between the walls (next to the 2 window frames) is approximately 88-90″, so subtracting a couple inches for the frame, I estimate the distance between anchors will be about 7′.

At 30-degrees, the horizontal force is roughly the same force as the downward force. I like David’s 1/3 down / 2/3 up suggestion for head/feet so will try that. Thus, you’ll have to add more tension to the rope to hold the same weight as the ropes move apart and the angle decreases. Question..are the angles measured before my weight 180lbs goes into the hammock(easier) or do I have to lean out of the hammock after my weight goes in (hard with integral net?) The calculator is incorrect. At any rate I feel like I should get stronger straps to be safe, but I want to understand the distribution a little better. Knowing that, I would not have paid for it.
