You’ll need a solid piece of wood or ceiling joists to attach your hammock to so it can safely hold your weight. Bob. It isn’t calculated. I can’t get the calculator to work. If you’re looking for help with rope hammocks, in afraid I cannot help you. Distance between Anchors [In my case I am trying to determine optimum distance between two posts I am setting in the ground, so this variable becomes part of my “what if…?” calculations] […] have. The suspension is what attaches to the hammock and spans and distance to the anchor point. You can either choose your ridgeline length (not automatically calculated) or the hammock length. 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. It is not clear to me, at least in the calculations for the height of hanging a hammock, if your measurements are from: the solid part of the hammock; the bar from which al the strings attach to the hammock,; or from the ring-shaped terminal points, or from some other point on the hammock. Hi! You can often squeeze or stretch a hammock into places the calculator say won’t work. The app was pulled because it isn’t compatible with Kindle. The only force exerted is gravitation. The ridgeline is going to be shorter than your hammock. The ridgeline is the length from the ends of the hammock along the line that connects them when the hammock is hung. The hammock should also have a curve to it, about 30°, so it should fit, but that hammock you’ve pictured has spreader bars, which isn’t intended for that style, and it will be tippy. Those strings are called the nettles that all combine to the clew. Making a progressive Web app wouldn’t be very much more than cleaning up the existing Web app to work well on mobile screens out of box. Ropes and webbing aren’t very good in transferring bending moments. Cord Tension [Is my supplemental cord for additional suspension strong enough?] – With the above details it suggests – Anchor points at 200cm and a 100cm suspension length at each end. Ridgeline (?). Thanks. I do need to update the calculator for bridge style hammocks that have spreader bars. I have been hammock camping for years and have just discovered that there is a correct way to do it. S = Sit height A bridge hammock. 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. Try restarting the phone. Please advise. If you would like a refund, please submit to the iOS store. Look for hammocks that are less than 10 feet long for that stand. Thanks . | Hammock Centre, Relax 101 - Perfecting the Art of Hammocking - Nikki Fogden-Moore, https://www.amazon.com/gp/product/B00O80MROA/ref=crt_ewc_title_srh_1?ie=UTF8&smid=A2RQVBHNLKPEYG&th=1. The web version should work on any internet browser. 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. L = Suspension length If you were building an ideal hammock hanging pergola, suitable for an assortment of hammocks (I currently own an ENO doublenest), what would be your ideal distance between posts (on each side), and what would be the minimum distance that would still work? Being light and compact hammock is much more easier to store rather than other sitting furniture like bean bags, chairs or eggs hammocks. Just bought the app for my android phone (Samsung Galaxy Note 4 This centrifugal action applies more force than just the weight of the stone. As the angle changes, the tensile forces increase on both sides. I didn’t take any offense from Ken’s question. Otherwise it is a great calculator and very helpful. Hi – and wow……….all I want to do is sling a hammock in a shady spot ! I’m trying to update the web version, but that will still be limited in having some native features, like a clinometer. The height & distances would still be the same? I can’t change the width of the span between poles. Also, one other question. The last developer update was over a year ago on August 30, 2015. Cheers, Todd. I hope this helps. Hmm. Weight The distance between the pergola posts is 8 feet, but can be adjusted to 9 feet wide. I can’t find an app in Google Play store. Are you using a ridgeline? When I take it down, there is nothing in the way, and only two pipes and the hammock to store. They have rope strings that have the loop. The app and the online calculator give me different numbers Knowing that, I would not have paid for it. It’s really a subjective measure based on your own preferences. It will be too small for most hammocks. You can’t lock both, it doesn’t work. I do appreciate your attempt to explain the physics to me and while I can grasp them theoretically, I’m just not wrapping my head around it completely. I hung the hammock in the house and it worked out great using the calculator and a tape. How can I download that hammock calculator as a jpeg ? No fields have been left blank. The calculator helps with a starting point, but you can modify from there for sure. DIY Barrel String Light Planters. R = Ridgeline length Thanks. 4 comments. Has it been added back? You can even download the Hammock Hang Calculator app for your smartphone so you have it in the […]. Also, I haven’t even bought the hammock yet 🙂 They had a safety rating of 325 lbs and they’ve been working great! Tape the blankets together – Use the clear packaging tape to attach the two blankets. High on my wish list is to have direct input of the variables and the ability to “lock” certain variables, such as hang point, when those variables are not adjustable. to be safety rated above 300 lbs. I was thinking on using a 2 x 4 long enough to reach two studs (between 16 in and 24 in) placing it horizontally. The Android app is no longer supported. Ultimately there are many ways to skin a cat..the calculator is but only one! 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?) It’s going to take me a moment to decipher some of this (I won’t claim at being a math expert). The calculator is it tuned (yet) for bridge hammocks. is shear force the lateral force on a single tree, or for both trees? I don’t want a bunch of holes in the walls trying to find the best place to span wall studs. I was considering a Wallaby, or something smaller, as a second hammock, and also as a possible hammock to hang from the backyard stand we have with the typical rope hammock with the spreader bars as my Roo is way too big. Online says ridgeline becomes 97 There are just too many variants to keep track of. The best places to hang are from to trees, one 4″ in diameter and the other 12″. Is this app still working? There is another one out there but I would prefer to support the developer hence the reason for the purchase, just like the purchase of the book. I would appreciate any guidance! You may not need any suspension depending on the length of the hammock. The app versions are accessible offline, but unfortunately I had to pull the Android version because of issues. I suppose you’re using the parabola equation (it would be more accurate with the catenary equation, but it doesn’t change by much). or am not doing something correctly? Was much easier in Mexico where the hooks are part of the cement wall and the hooks failing seems rather impossible! Perhaps the problem is that the calculator does not consider a distributed load?? Under the Trees. To make that happen, you’d want a distance of at least 12 feet to accommodate the tarp. The force calculation may change if the hammock is not level and even, but I suspect that it’s not far off. Possibly a dumb question. Calculate 83% of the length of the hammock as a starting point. Most western style hammock stands are designed for net rope spreader bar hammocks so the height hang point is lower. […] the hang calculator to determine the hang […], […] Hammock Hang Calculator | The Ultimate Hang […]. Or maybe I just need to go with what you said. Or update the app, either way. I just noticed something weird is happening when you select the Metric radio button more than once – the numbers go crazy. Thanks. The only thing you can change is how this force is distributed (ie vertical or horizontal) . Other than this, there is not too much to know. Which calculator are you using? I am a hammock rookie and ran across your calculator. I have not read all 279 previous comments, so perhaps this has already been discussed? (I’m sure this is quite simple but am having trouble getting my head around it!). I sometimes get “missing apps” in the app store too. Could you tell me how to calculate the ‘virtual’ ridgeline? It is specific hardware that has issues. Are there plans for a Windows Phone version? I’ll explain. Which means the only force it can transfer is tension. As to this web calculator, it has to make some accommodation whether you input the ridgeline length or not. Ideally the hammock handles should be approximately 11ft 6in (3.5m) apart and 6ft (1.8m) high giving the hammock a nice loose curve. Being light and compact hammock is much more easier to store rather than other sitting furniture like bean bags, chairs or eggs hammocks. there is another 13″ of rope and hardware on each end) Strap length (includes rope and hardware): 66. Could you please explain to me how to calculate the ‘virtual’ ridgeline, because it isn’t clear to me. For steel you’ll just need to use different bolts or screws. Progressive Web Apps are just HTML5+JavaScript and have some tags that tell browsers how to store it for offline usage. Too much curve in the spine for some.
