Jaco and OldEng,
Thank you both.
Jaco, are you suggesting the 1-1/4 tube with the 3/8 wall thickness?
Also I'm having trouble finding .375 thickness ERW so DOM may have to do.
Thank you all for such gentlemanly and scholarly responses.
To clarify, the span is 6' 4" which happens to be the distance between 2 walls in my home. My grip width is in the 24-36" range. I'd like to minimize deflection.
I have found this tube which is 1 3/8 diameter with 3/8 wall...
OldEngr63: I found a 1 3/8" pipe made of 7 gauge 1008 carbon steel.
7 gauge is 0.1793" and 1008 steel has a Young's modulus of 30 x 10^6.
Using your formula, and using 65" as the length and 200 lb as the load, I obtain a deflection of 0.0317 inches which seems good. Almost too good ...
Am I...
Thank you for the timely and helpful response complete with equations.
I am not sure what the Young's modulus of the materials at my hardware store are so I'll have to make some educated guesses.
Another approach that I am favoring now is to use a beam as a support and to hang rings off it...
Thank you so much for taking the time to reply.
My request about no deflection may be too literal. It can have some give, so long as it doesn't permanently deform over time.
I will also take you advice and try to figure out a middle support but it's not looking promising.
Thanks again,

Hello,
I am looking to install a pull up bar in my home.
I have a 6' 4" span. I weigh 200lb.
I'd like the bar to have a round cross section so that I can grip it directly. Ideally the outside diameter of the pipe should be 1.25".
I don't want there to be too much spring or give in the...
