How much weight can drywall and the stud behind it take? I think it is a 2*4 Answered

 I am making a set of gymnastics rings so I can do strength training at home.  I almost have a planche and i hope to get it this competition season.
I want to hang the rings from the ceiling with these:harborfreight 92306
and attach the rope to the wall with these:harborfreight 66458
The rope i will use will be this: harborfreight 92463

For some reason i can't post links


Drywall  won't take significant weight in that direction.

If you're lucky, the ceiling joists will be 2x6 or 2x8. (The latter is more common these days; older houses may have the former.) Even so, hanging on two rings is putting a very localized load on them, and likely some sideways load. I wouldn't want to risk my house on tis, but if I _had_ to do so I'd want to install cross-braces between the studs to keep them from moving in that direction... and I'd want the rings affixed to something that transferred the weight to the TOP of the joists, rather than tugging on hardware that could potentially pull free.

In other words, I agree with Burf: unless you can get access to the ceiling's guts -- from the attic, or by cutting holes in the ceiling -- and do this carefully so the force at any point is no worse than jumping up and down on the floor upstairs would be -- I wouldn't even think about it. And I really wouldn't want you doing it to my place without getting better advice. Especially if they're really 2x4's, which are nowhere near as resistant to flexing as the 2x6 or 2x8 would be.

Even hanging a ceiling fan requires some care to keep it safe. You weigh at least three times what a ceiling fan does, and a ceiling fan isn't a dynamic load.

Based on the information you have given, the only realistic answer is, "not very much."
The load you intend to put on it isn't static, and there will be bending and flexing of the joists dependent upon how close to the center of the span the weight is placed. Even if the joists don't actually break,  eventually, the nails or screws fastening the the drywall will loosen and the drywall will sag.
I would never consider suspending anything that weighs more 15-20 pounds from 2x4 ceiling joists without bracing and possibly doubling the joists.
My recommendation is that you get someone who knows what he is doing come take a look at what you want to do and tell you the best way to accomplish the task.

 I think it would be static, because i am just doing strength training, no much if any swinging.  I way about 120.

No, every time you put you weight on the rings, you cause the 2x4 to flex down. When you release, it moves back up. Static means the weight would be there all the time, like a light fixture or garage door opener.
One other thing you didn't mention, is how you intend to attach the mounts or brackets. Drilling holes for bolts and screws weakens the joist.
My recommendation still is that you get advice from someone who knows.

Seconded - When in doubt, ask - or supremely overbuild. 

Worst case scenario, build a beam out of 3 or 4 2x10 screwed and glued - then support that on either side of the room with a 4x4 or 6x6 post.  Use Use the ceiling ONLY to keep the beam centered, not to carry any load.  Secure the verticals to the wall studs - again, not for weight support, but for vertical stability.  Rest the supports on wide baseplates that can spread the load over multiple joists if you don't have a concrete floor.

could i do something like put use 2 4x4 posts and a 4x4 nailed+glued to the top of the 2 4x4 posts and then drill a few holes through the supporting 4x4 posts and screw it into the wall studs their.  Or could i screw a 4x4 into the wall stud and  put a 2x4 on each edge of the 4x4.

That's exactly what I suggest; but I would use something beefier than a 4x4 for the horizontal beam.  Overbuild.
