Structural integrity of a hanging tent platform 1

[treeclimberr]

I am planning on building a tent platform that will hang from four trees. My plan is a 10'x10' platform constructed with 2x8s with 15" center to center joist spacing. Flooring will be the lightest plywood I can find. Will this platform be structurally sound if hung by all four corners, especially if the strain is not 100% vertical, but more along the lines of 45 deg.? All the platform will hold is a mattress and myself with a simple A-frame covered in shrink which I don't anticipate will add to the weight significantly. I'm planning on using four 1-ton come-alongs in each corner with 3/16 galvanized cable.

My fear is that the horizontal component of the wire strain will prove problematic, but I may be mistaken. Any specific building additions/precautions I need to include?

Any advice would be greatly appreciated.

Keep tension in cables. Be weary of eyebolts. Free body diagrams. Got it!

Earthsuntech-
Thank you for those diagrams-- very helpful to visualize. "Crushed like it was made in tooth picks in heavy winds"-- maybe I'll have to relocate during storms or maybe that's part of the thrill of being alive!

I'll be back at the land in a little over a week and can get a better idea of the tree orientation I'm working with so I can make a wire cradle work. Will start constructing shortly thereafter-- pics to follow!

Make your tree platform triangular and you won't spend time trying to get tension distributed evenly.

Thanks for all the help! Trees ended up dictating most of it but I've been up for about 3 weeks and it hasn't fallen yet!

Cables attach at all 4 corners...looped around pipe nipple then back through. Trees allow for almost completely vertical forces. Swinging is dampened by horizontal cable running underneath the platform to two trees. Perfect!
