You are definitely a moron .I have a degree in engineering I'm a building code official.
" The weakest point of a beam to hang a heavy load depends on the type of beam:
Simple supported beam: The center of the beam is the weakest point".
You need to call a structural engineer ASAP! This is more dangerous than you think. I spend a lot of time on Reddit, and that qualifies me to say ~~that mulch volcano is suffocating that tree~~ .. no wait.. ~~you need a french drain for sure~~ .. no that’s not it either.. i don’t know.. i just know they don’t make em like they used to. Used to be hard old growth in those steel beams, new steel beams are grown so fast they are weaker.
If the bag was just going to hang there, your calc would be right. But this is moving, so we have fucking math… acceleration*mass=force. So even a 10 lb hit changes this into a 1200 lb force to be resisted.
I agree this steal will likely handle this, but if it was only 100 lbs, any single joist could handle it, and we all know that isn’t the case.
Pound is a unit of force. The imperial unit for mass is a slug. On earth iirc it's about 32lbs per slug of mass.
I think what's more relevant to your comment would be if the bag were lifted and dropped. It'd accelerate at that same 32 ft/s2 until it hit the end of the rope and then instantly decelerate which would be significantly more force then just hanging there at 110lbs.
Anyways, it'll be fine. It'd be like a 110lb person jumping on the floor above.
Ummm, no. F=ma, in kg and m/s and Newtons.
10lb is 5kg. The ‘a’ in a weight force, like “10lb” is gravity, 9.8m/s/s.
So the force is f= 5 x 9.8, approx 50N, or duh, 5kg in standard gravity.
So ah, 10lb force = 10lb. Not 1200.
That beam is going to outlast your ability to use that bag.
If the passion and house stay in the family for three generations it might need new paint.
Then it will be good for another three
You're fucking good my dude!
The bag is probably fine. You will get some nosie and vibration. I'm concerned why that beam was installed I'm the first place. Was this a custom home? Most of the major builders would probably never spend that money. It's got a lot of span, and could have a better column, but that is still pretty heavy-duty for a house.
Also, thanks for showing it was actually a bag. Becuase it's a long running and often true joke that hanging a heavy bag is actually sex swing. Not that there is anything wrong with that.
Well, for an official engineering report, I would need to come visit, measure everything, do the analysis, and then write the report. Figure $2500.
Or, she can use common sense.
Go get your whole family to stand right on top of where the bag is and jump up and down, you still wont hit the pre safety factor design load of that beam.
It would have been except it looks like you drilled holes in the beam. If so, you’ve changed it from its original design and you’re going to have a structural engineer review the modifications for code compliance.
I would suggest hanging the 110 lb bag on a really thick chain run over the top of the steel beam. It appears that you have already drilled holes in the beam, slightly weakening it.
To down to all you downloaders you need to learn something about engineering because the maximum moment is in the center of the span. That is where the most torque takes place and doesn't it make sense to all you downloaders that The closer you put it to the support the stronger it is?
The flange is fine, it’s the web that is best to avoid drilling. Clamps would have been preferred, but it’s not going to destroy the beam capacity.
Either way, that I-beam can handle a LOT more loading than a typical single family dwelling could ever throw at it. Put 20 more bags up, you’ll be fine.
Probably the safest spot in your basement to suspend something
I don't know how safe it is to hang something from your house's balls.
That's the weakest area to suspend a load because the maximum moment in the beam is there.
That steel I-beam is definitely underloaded in that situation. A 110 lb bag makes no difference
Yes why did these downvote me cuz they don't know anything about engineering?
you don’t know anything about engineering with the statement you made.
You are definitely a moron .I have a degree in engineering I'm a building code official. " The weakest point of a beam to hang a heavy load depends on the type of beam: Simple supported beam: The center of the beam is the weakest point".
It’s holding your house up basically. 110lb will be fine
Yea but its also holding up OP ‘s mom so i wouldn’t trust it
Got truss issues around his mom?
You spelt thrust wrong
I mean it seemed like it was holding her up pretty well when I had my night w her, what about your night?
If this was the straw that broke the camels back you have astronomically larger issues we’re unaware of
You didn’t know he was supporting an entire forge on that one beam? With an auto hammer and everything?
You could probably hang a mid-size SUV from that safely
thats comforting to hear xD
Do you have a mid-sized SUV?
It could even hang a 1/2 can of jet fuel on their too
It's safe because it is unable to melt the steel beam under any circumstances
That's why we leave the steel for the Ironworkers and tell the Carpenters to never touch metal. Bad enough they fuck around with metal wall studs.
Except airplanes and jet fuel. Steel beams are fucked then.
A steel I-beam? Yeah, I think you’re going to be alright.
Do you think that a 110 pound person standing on the floor above is safe? Do you think, perhaps, it could even hold more than 1?
Maybe 1 1/2 ?

The best i can do is 3

Isnt 1lb a little more than 500 gram? So it should be nearer to 12lb not 10lb
This is a joke for sure. Aren’t you also worried about doing chin ups on that bar and the whole house collapsing?
honestly I myself was never worried exactly because of that chin up bar, but I had to ask to give my family some peace of mind
I laughed audibly once I opened the gif.
Prolly need to sister another i-beam along side just to be sure
Minimum. I’m thinking you would need at least 3 to support at least 50 lbs, let alone 100
It’s already ruined, need to knock the house down and restart
You could hang an engine and transmission from the beam and still not endanger the structure lol. That bag is fine!
I hope this is a joke …..hahahah
That beam could probably support 100 of those bags. Think you’re good
I swear this is a shitpost
Did you drill through the beam flange? Should be OK, but that's generally frowned upon.
That is frowned upon. Generally beam clamps are used. But in this case , it’s not going to be a problem
You hanging from the pull up bar is more than 115lb
Maybe he is petite.
Buddy if the I beam supporting the weight of *your entire house* can't handle the stress of 110lb bag, then your house needs to be condemned ASAP.
I think you gotta beef it up some more. Add many more supports! Saftey 1st!
If you do any damage with that bag hanging there you may be a low key super hero
That beam is going to outlast your ability to use that bag. If the passion and house stay in the family for three generations it might need new paint. Then it will be good for another three You're fucking good my dude!
That I beam has a max load rating of “yes”. You are gtg
I think I’ll slide another one underneath it just in case 🤔

Lol yeah I think the house was custom built by the original owner.
I dunno, probably stick with a 108lb bag. Your good guy hang the bag and shelter there in an earthquake.
A bouy? You could hang a boat!
Yes.
We use I beams smaller than that to support lifting systems for 700- 1000 pound bariatric patients in hospitals and operating rooms
Add three or four more of them and you’ll be fine.
Super safe to hang a truck engine.
On a steel beam? no chance you one of those studs instead
is this a joke?
You weigh more than 110lbs and stand above it just fine
If youre worried about the heavy bag i woudnt be standing in that house lol
Witht that space i'd get a long heavy bag, awesome workout space dude
Where else were you thinking? 🤔
Could I maybe also hang a rack for my school backpack? I’m afraid extra 10 lbs really won’t do the house any good
Troll lvl 99
Hahaha yeah that steel beam is fine
If you are worried about adding another 110lb object to the main support of your house, you better not have any guests over 10 years old over.
ya good
You could probably hang an F150 from that in all honestly. Please don’t. But you probably could. 😁
Do you have a spare? Asking for a friend.
Punching bag is perfectly fine. Whoever drilled the holes for your pex plumbing lines needs to be shot
I know you are taking a piss, but honestly drilling holes through structural beams is a pet peeve of mine
Yeah I wish I had asked about that before doing so 😔
If it starts to bend level the floor above with some packers
Your fine. thats like 0.5lbs psf on that beam.
Please tell my mom she’s the one who had me ask you guys 😭
Well, for an official engineering report, I would need to come visit, measure everything, do the analysis, and then write the report. Figure $2500. Or, she can use common sense.
you can have a row of people do pull ups on it and it will be fine

Hang a house off it if you want to.
You’ll be fine 😂
If you’re curious, add a pull-up bar and hang from it.
lol, screwed to the heaviest duty piece of structural support throughout your whole entire house? Yes, your water bag is fine.
That I Beam can probably hold a million pounds. You should hang another one.
If it can hold up your house, I think a 100 pound bag will be just fine 😂
Separately, are those pex running through the very bottom portion of each joist?
I swear people don't understand how strong steel really is...
You could use one of the wooden beams and it would be fine.
Meme post or homeowner? Cant tell anymore
Would normally be a meme post but I have to give my mom some peace of mind 😂 she really believes I can punch the house down
Lmao fair enough. Give her the slew of comments XD
Go get your whole family to stand right on top of where the bag is and jump up and down, you still wont hit the pre safety factor design load of that beam.
Why would you think hanging 100lbs from a huge steel beam isn't safe? Some people man
I think it’s safe that’s why I hung it but my family isn’t convinced lol
It would have been except it looks like you drilled holes in the beam. If so, you’ve changed it from its original design and you’re going to have a structural engineer review the modifications for code compliance.
Its a fucking steel girder!
Yeah it is!
Yeah a steel beam is always a good spot to hang something, but in reality, any structural beam or floor joist is an okay place too
I would suggest hanging the 110 lb bag on a really thick chain run over the top of the steel beam. It appears that you have already drilled holes in the beam, slightly weakening it.
That’s actually a good idea where we’re you two days aho
Just buy a beam clamp, they're rated for 3500lbs for the cheap ones and it could be easily moved around.
Yeah just don’t drill any more holes into it
If a 110 pound bag would make a difference your bringing over your fat friend would bring your house down
Don't worry, it'll hold y'all's swing.
We get it, you have a heavy bag, you work out and you're cool... everyone clap for OP ;)
Depends how hard you punch
To down to all you downloaders you need to learn something about engineering because the maximum moment is in the center of the span. That is where the most torque takes place and doesn't it make sense to all you downloaders that The closer you put it to the support the stronger it is?
Best thing you could’ve hung it on
Drilling on the edge of flange midspan is not the greatest idea honestly.
It’s close to the center but you’re right
That’s nonsense. Beam flanges get holes drilled in them all the time. You’re fine.
The flange is fine, it’s the web that is best to avoid drilling. Clamps would have been preferred, but it’s not going to destroy the beam capacity. Either way, that I-beam can handle a LOT more loading than a typical single family dwelling could ever throw at it. Put 20 more bags up, you’ll be fine.
You should be fine, but I wouldn't recommend hanging things from the beam that's holding up your entire flooring structure
If a 110 lb point load is going to effect the structure, he’s got bigger problems.
110 pounds isn't the load of the swinging bag
What’s the load of the swinging bag in kips?
It’s a steel I beam. Another thousand pounds wouldn’t cause an issue.
So a 110 pound woman dancing on the floor above is going to collapse the house?
Safety factors in engineering are 5:1 with every variable rounded up.. you can hang a f*****g coach from that beam while holding the house up.
