Thread: Why 30 degrees?

  1. #1

    Why 30 degrees?

    I've read plenty of posts where people talk about a 30 degree hang but after a bit of a search I can't find out why it's important. Is it something to do with the forces applied to the suspension system and a 30 degree angle lessens the weight or is it just a comfort factor?

    At 30 degrees from horizontal the load on each end of the suspension is equal to the weight of the person using the hammock. So if you weigh 200# then your suspension is being pulled to 200#. Of course that is the static load. Shock load can be many time higher.

    As the angle of the hang gets shallower, the load on the suspension increases.

    Math- the calculation of the tension applied to the string holding you up increases greatly as the angle between your suspension and ridge line approaches 180*.

    Or, zero degrees. You say toe mah toe, I say toe may toe?

    Wow great info.
    I had no idea the 30 degrees was for minimum applied weigh on the suspension system.

    I always thought it was the required angle to get the proper sag for flattest lay in a gathered end hammock.

    One never stops learning on HF :-)

    i always get " hung up" on math ;] i cant remember where i read it on here but if you put your hand in an L shape with your thumb straight up at the point of contact to the tree and your index to the point of connection of hammock to suspension and that line making the longest side of the triangle right there is your 30º ( btw alt-0 is degree)
    Every time I hang in a tree I get a coconut to the head.....stupid coconuts

    For me 30-35 degrees is just about right for maximum comfort and restful sleep. Too flat the sides fold up around you and smother. Too steep and it's harder to lie on the diagonal.
