    Single point hanging??

    Anyone know what this hammock/tent/chair is?


    I did a bit of searching and can't find much info. Now my wife wants me to buy or manufacture one. Not much to go on but a photo on FB.

    I'm diggin that setup Alukban! Very nice use of, "what ya got". Plus, what's not to love about a structural ridge line ya can do pullups on

    u.w.

    Can any of our structural engineers figure out what the load would be on given say a 12 beam, a hammock hanging at the ideal 30 degrees and a 250 lb load?

    Length of the beam actually doesn't matter (for compressive load) it gets complicated with flexural load - you need to know the flexural modulus and moi of the beam. It changes based on shape and material.

    For "cocktail" napkin calculations though:
    compression on beam = load / tan(angle)
    in this case 250lb / tan30 = 433lb compression
    incidentally - this is exactly the same as the force on two trees holding the same hammock.

    torque on end of beam = (Length of beam / 2) * (Load / 2)
    --*note that this torque is if you support the beam from the middle, if you support the beam on the ends, as shown above - there is negligible torque.
    Qualified to do almost anything with almost nothing. Ask me how!

    That child is having way too much fun. Is she a member? She ought to be.
