My mechanical & civil engineering usage is gone as the last time I did that was in Freshman year & my major went in another direction, but I've tried to be as thorough as possible using a prior question.
PS: If this has to go to Physics SE, please let me know or move it.
Based on this question I posted on DIY:
What kind of Extruded Aluminum sections to replace main wooden frame on this DIY project?,
I received a very detailed & interesting answer here from Ben Welborn pointing out various factors around angles, lengths loads, torque, Center of Gravity/ Mass etc.
I still have to completely digest the math/ calculations, which I'll have to do with my uncle.
That question was centered around the vertical sections, whereas he did help with determining some of the detailed loading parameters.
Here, I am curious to find "In what position would a human be exerting Max Load on the horizontal rods, and what would that load be?"
Human body weight: 200 lbs for simplicity. No added plates, dumbbells, barbells etc.
Rods are 36-40" wide and 1-2" in Diameter if that helps.
- No aerials & similar momentum; i.e. Handclap pull-ups.
- Static positions as shown or what you guys can think of,
- Dynamic positions/ movements; Hanging V-up, i.e. Straight vertical Hang and full leg sit up from the waist, but in steady control (I guess the 90 degree L-position would be max leverage), NO Crossfit style momentum.
- No purposefully destructive positions/ movements as suggested in one comment;
- The worst case scenario I believe would be to have Žydrūnas Savickas at the top of your structure (or at the midspan between two supports), resting his feet on the wall, grabbing one of the rungs and then trying to do a 524kg deadlift.
Please do not constrain yourself to only the given examples of what people are able to do, but I'm sharing examples to kick start things. Positions vary in being 1 or 2 handed/ legged, both on same or different horizontal rods.
Which of these or other positions/ leverage you might think of would be position of Max Load?
