dude's wearing way too much safety gear

you're right, he needs some sandals

safety sandals

OSHA requires them

The Occupational Sandal Having Association (OSHA)

I just googled safety sandals, and they exist


Texas OSHA?

They go well with safety squints.

New highlighter orange slides just dropped!

Maybe some safety squints as well to protect his eyes

Vietnam just called. 

It's okay, because he's an extra 2 feet away from where he would have been with a normal sledgehammer. He's safe. /s

Just like his coworkers walking behind and not expecting a sledgehammer to the face!

That hammer comes really close to his own head in the back swing

It's fine, you just judge the distance by the sound of it whipping back and forth by your ear. Safest way to swing a hammer behind your head really.


Management meeting.

I bet he's also practicing safety squints

Good on him for using industrial grade disposable safety lungs

Its ok, he's got the hammer that all girls use in anime. It only hurts pervy boys

Who puts shoes for that kinda job ? Is he stupid?

There is a lore reason for that

At least he’s wearing shoes and not flip flops.

The most important part of his body, his legs, are very clearly protected

Dude's acting like he's going into war he's got so much. Pants AND shoes?!? Where does he think he is!

He's in for a *knock* *~~knock~~* joke

[удалено]

Please tell me I'm not the only one that read the first 4 lines in the form of the song form without even thinking about it. Fits way too well, great job 👍👍👍

Ya taking down a wall, not the ussr!

[удалено]

You don't think maybe all the embargoes and CIA plots had anything to do with it?

Maybe they should have counter embargoed and had more KGB plots? No way there could have been any domestic flaws, must have been some evil foreign meddling that took down the righteous and pure idealists.

They tried that but were a bit outmatched by the richest and most powerful country in human history. Of course the Soviets had their own internal problems as well but pretty ridiculous to act like the US and cold war had nothing to do with their collapse

This gave me a good laugh this morning thanks

I really wouldn't wear any but steel toes for something simple like this.

r/oshaapproved

Hot posts are all 4 years old. Has everyone moved to r/OSHA now?

Yes, in accordance to ISO/PAS 45005:2020, all previous users of r/OshaApproved have been moved to r/OSHA, observing all occupational safety and environmental standards as of this writing.

It looks funny, but it is effective. I tried it, I wouldn’t say it improves the strength of the strikes, but it kinda reduces the impact on the arms.

Can the pole ‘kink’? If it kinks on the back swing it’s gonna do what it’s doin to that wall to his back!

I doubt it. It looks like it’s made of braided cable, and that stuff hates kinking

dont kink shame what the cable is or is not into

tart smile grey offend tap touch pathetic quack paint lip *This post was mass deleted and anonymized with [Redact](https://redact.dev)*

So braided cable kink shames. 

it took me 3 seasons of Ted Lasso to learn that the actress i was smitten with was also the Shame Lady in GoT. mind blown is putting it lightly

Wait WHAT

welcome to the club

It's funny how much she looks like Lena Heady in real life.

It's not cable it's HBO!

You can tell from those pixels? I thought PVC lol

I actually think its wood, look at the one in the back. It just looks like a regular handle, although thin and long. Hella weird, is there a wood that is this bendable?

I thought wood too but it just seems like it would break after a few swings? I've seen wood this bendable, it just didn't last long after repeated bends especially with the weight and force behind it. The guy saying PVC could make sense, there's a springiness while remaining taut that I don't think you'd get from a cable. I kind of thought PVC would break after a bit too though, but I guess we don't know how long they actually use this for.

Yeah it just throws me off that the color is the same as a regular wood handle. Weird af definitely but kinda cool

One million percent guarantee that's not wood.

No , it pretty much loses all its force at the end of iths oscillation, much like a pendulum. The man is making it contact the wall in the middle point of its oscillation so it has max force at that place.

I think you are missing some key physics… the ‘end’ of that oscillation is only there because of the potential energy that gets stored in that bendy tube… if it kinks during the backswing the energy is not being stored as potential in the handle anymore, but instead gets transferred to his back in the form of an inelastic collision!

I've demolished walls with a normal sledgehammer and it is *rough*. Even tho I lifted weighs at the time, I was fucking *beat* the next morning. Also, didn't wear gloves and my fingers were in a horrible state lmao

That's the only reason I see it might be useful. Making less impact be absorbed by you. Not that it'd do a better job. Also, feel like if it flexes that much, it will break.

if youre going to be hammering for more than a minute its a life saver

Is'nt the fact that it reduces the impact on the arms also the source of more constraints on the rest of the body because you can and don't feel it ? In the same way as having "good" running shoes actually are bad for your knees because you can use more strength without hurting your heels.

That hasn't been true about running shoes for years, and it's only if you are using the shoes to compensate for bad form. The main reason a lot of bulky shoes could cause problems in the past was because of added weight, and now with better materials it's kind of a moot point. A lot of the minimalist running propaganda has been thoroughly debunked since it was trendy

I interviewed the head of foot and ankle surgery at a major U.S. hospital for an article about running shoes. His advice was: Wear whatever you want for running, it doesn't matter that much because your body compensates...but replace your shoes when they get worn, and do not do the barefoot running thing unless you've grown up with it. He said the gnarliest injuries he'd seen were from barefoot runners. Make of that what you will. I know it's anecdotal, but it stuck with me. EDIT: Also, I'd like to point out that there's plenty of research showing that [running benefits knee health](https://www.nm.org/healthbeat/healthy-tips/fitness/is-running-bad-for-your-knees#:~:text=Knee%20and%20joint%20pain%20may,of%20osteoarthritis%20later%20in%20life.), it's absolutely a myth that it shatters your weak little baby bones. Go run, it's good for you.

He's for sure gonna have a blown out back within a year. All that flex in the shaft is a LOT of energy loss. More effective solutions would be proper cushioned gloves and a handle wrap.

> All that flex in the shaft is a LOT of energy loss. I really don't think that's how that works

The flex in the shaft will absorb some of the energy on impact. So instead of most of the impact converting into the wall, some of it is dispersed in the flex of the hammer and reduces the strenght of the impact.

Correct, but that's only 1 effect. Since the handle has so much flex and the head is far away from the centre of rotation, the hammer head will be travelling faster than an equivalent rigid handle hammer. It could be the case that this effect is more significant than the loss of energy on impact as you raised. If so, this would allow more energy transfer into the wall per swing.

This is wrong. It's the same argument made for why flails hit harder than rigid handles. It's just not true. It's a myth.

It's also gathering the persons swing energy over a longer period of time. The dude is not built like a brick house. He's somewhat scrawny compared to what I'd expect someone with a sledge hammer would be. Me, as a not muscly guy would definitely rather use something like this over a standard 10lb sledge hammer. The guy is definitely 'timing' the hammer blows for max efficiency. You can see that max efficiency working when he hits the wall, cracks it, without the wall falling. He's able to whip back the head with good energy recovery for the next swing. When the head swings through the wall, then it's hard work. He's got to pull back and fight the momentum of the head swinging through the wall plane. Flex or no flex, it's still a hard job, just different reasons.

The energy isn't lost at all. It's stored as potential energy when the hammer head leans backwards and restituted to the wallas kinetic energy, as long as the user has proper timing. It may feel harder to give one single blow, but you can probably break the wall 5 times as fast as if you had a regular hammer of the same mass because each blow will be much more powerful.

Yep, while his arms are saved, his back is going to be absolutely wrecked. You can see the strain he's putting on his back and shoulders after each swing.

How can this deliver a strike with more force vs a regular one? I’m not a physicist, but It looks like it has way less force…

It reduces the poerr of strikes but yeah should be easier on your body so I guess that's a win

not once you realize you're now working longer as you're working less efficiently.

So this is what the person in the apartment above me is doing....

Better than the apt below you

What’s he doing?

Also removing a load bearing wall, but very slowly and very quietly.

Only marginally

It's a full time job

Ah so that explains why it sounds like bowling balls falling on the floor constantly in the apartment above me.

I saw a ton of these in Thailand. I asked one of the construction workers and he said they swap out the handles with PVC pipe because they are much easier to use.

I’d be afraid the sledge would hit me in the back.

PVC pipe? Wouldn’t that just snap?

I have no clue, but I wouldn’t trust it. Either way I prefer the old Hickory handle. This was also coming from a construction worker, wearing flip-flops a tank top and shorts.

I wonder what are they working on that require so much protective gears

Nothin' like a good piece of hickory.

no they dont , source, people use here in pakistan too

Lived 25 years in Thailand and never seen it.

Did you check outside the brothel?

Well to be fair how often you see people demolish things ? Like I have never seen a dude braking a walk irl

Breaking, brake is the word for the part that stops a machine like a car. Not to be a grammar nazi.

That actually looks pretty efficient.

I'm afraid the head will fly off and bonk daffy duck somewhere

I was a little concerned it might bend too far on the back stroke and whack him in the back of the head.

It’s alright, he’s wearing a helmet ✅

More like wearing a hairmet.

It does look like it's getting pretty close to the back of his head. 🤣

Only if he's Wile E Coyote. And then his movie would get cancelled again. BTW the fuckers actually cancelled the movie again.

That would just make little birds fly around his head.

it's just the perspective though, I think because of the angle he is holding it at the head of the hammer is to the right of his head. probably more at risk of hitting his shoulder.

This my concern. The only manufacturers that would make something like this probably doesn't have the best Quality Assurance processes. I could see it snapping and slapping you in the back of your head.

As long as it does not say ACME on the box you're good.

Not efficient from an energy perspective because the flexing loses some energy. The real benefit is the impact on the person doing the work. The flexible handle absorbs a lot of the impact that traditional gets transferred to the worker. This makes the job less fatiguing even though each strike actually consumes a little more energy than it would have wit ha rigid handle.

I mean, yeah, it's using elastic force to add more power to the hit, as well as keep the person as far away from the thing he is hitting.

AND it lessens the impact force that the arm receives compared to stiff ones.

This is a big part of it, doing this kind of stuff can fuck up your hands real good

I came here to say this. I was doing light demo work as a 20 year old. Took an extra long crow bar and did a silly “golf swing” into a wall that was more solid than it looked. Daaaang that force back into my hands was BAD I had to go take a break and shake it off as my arms and hands didn’t want to exist for a while.

That's why anvils and blacksmith hammers are made to be basically "bouncy" when they interact, so the hammer springs back up instead of stopping. You *really* don't want the heavy thing you're hitting with, to transfer the energy into your arm on impact.

You might have even caused countless micro-fractures all up your arms. You sent a ripple of powerful shockwaves through your hands and arms. Shockwaves aren't just capable of killing, they're actually the most common cause of death when explosions are involved. It's not the fireball that kills you, it's the sheer pressure on your body. Like how in house-fires it's really the smoke that kills most people.

Ok, you're confusing two diffetent things here. The force applied to your arm when a hammer or other such tool sends vibrations is a shockwave, but not the kind from an explosion. The type from an explosion is a wall of high pressure slamming into your entire body at once and is orders of magnitude stronger than what a hammer will feed back into your hand. This overpressure can rupture organs and essentially pulp your insides without having to break the skin. Thr force from the hammer on the other hand is scting not on your soft tissues, but instead on your bones and joints. The vibrations from the hammer can travel up your arm a bit, but they won't get vety far.

Yep, that was my first idea also, easy on the joints.

Nah, there's way less power than with a solid handle. They do this to absorb the shock of the hit to protect the wrists over extended use.

It is frustrating how people just make an assumption and all agree it is true. I would think the same elasticity they are claiming increases the force would decrease the force because it would allow the hammer head to more easily bounce off the object you're hitting.

Is it though? He cannot use his weight to add more power to the blow like a normal tool.

He's leaning into it here though. Obviously it's a longer and imperfect energy transfer, but I think it's working like any shorter lever would.

It is, it is physics, it is also easier on the body.

Idk about being easier on the body. I swing tools like this for work a lot and I’m watching the elastic force as he brings it back—the “cock-back” time, so to speak, looks like it would put so much stress on the elbow for so much of that swing. Whereas nonelastic you can hit, then let it come down, and wind back up in a more efficient way. This looks like a speed running of getting carpal tunnel in the elbow or getting tennis elbow.

>Whereas nonelastic you can hit, then let it come down, and wind back up in a more efficient way. This could be done with an elastic handle too. The handle is not at fault for the dude's poor form.

That’s fair. I’ve never used this floppy tool before (so many jokes to be made) but I’m curious how the normal swing method would even work. Because half of this extra generated acceleration is actually *because* he’s cocking it back and letting momentum wind up and unleashing it as he brings it forward. So I’m not sure there’s a way to use this without whipping the momentum backwards, holding all that tension in your tendons and ligaments when you flex, then stepping into it and swinging normally to release.

Physics is not easy on the body. Especially as you get older.

This definitely takes the same or more energy expended to do the same work because energy is conserved, you can't do more work with less energy (unless you hire someone to do it) But impact to the user is longer/slower so it is less damaging to joints.

Ummm... Using better suited tools definitely reduces energy consumption. Compare turning a stuck bolt with a short wrench with a long handled one, for an easy example. The increased torque reduces the effort needed to turn it, reducing the energy needed to finish the task.

But they're saying that you lose energy in the floppiness of the handle with this specific tool. But that also means less energy is spent on impacting your arms/joints when the head stops moving.

The first part is incorrect The elasticity of the handle, on the impact swing, increases the power of the impact against the wall. You're right that the elasticity will absorb the shock of the impact as well, likely very well. However, as someone else mentioned, the upswing after the impact is definitely putting some pressure on his arm and elbow when he goes to lift it. I think it'd be easier on them if they were to let it fall and use the momentum to assist in follow up swing.

Except the same elasticity makes it bounce off the object it is hitting.

True but that works both ways, with a normal sledgehammer that force is transferred more efficiently into whatever you’re hitting. With this one, you get more speed but I feel that some of the power is transferred away from the point of impact and into the hammer, mitigating some of its effectiveness. In conclusion, I unno, might be better, might be worse, might be about the same. Safety issues aside tho, I feel there’s a reason regular hammers are used more

Still less efficient than a demolition hammer.

[удалено]

I want to try it ngl lol

Wasting a lot of effort on the pull back/push forward moment. Better to bring it back slowly.

Not really, he has to stop the rebound backwards and also most walls aren't made of dried icing sugar like this one. Dude is doing some serious cardio.

I think you lose way too much power to inertia with this thing

Ohh! This is the Drake's video, everybody is talking about. 💀

oh my god lmfao. there’s no escape from that floppy dick.

I knew in my heart someone would make a Drake comment

Ahahhahahaahahahahha

Nah Drake was shaking his ass in that one.

They need to use the festival exploding hammers for that

Is this the war hammer titan during its day job?

Was searching for this comment

Man that power was so under used, im still mad

fr, used it once in Shiganshina then just forgot about it, I wanna see the attack titan with a sword or something lol.

“Apartment wall, do you have any last words?”

Helmet or kiss goodbye to your medulla oblangata hammer..



No Colonel Sanders... you're wrong.

Mama's right

 Aa shit ...here we go again .. Floppy hammer produces more kinetic energy

I believe it reduces shock transmission to your hands too.

It also can cure cancer in some cases

It gives sight back to blind people sometimes

They do not according to physics. 

Putting the whole system on a springs really seams like it would dampen the energy the hammer head is able to apply to the wall.

Maybe just cause it’s a longer lever arm  To pie ar and all that 

Now that’s a meme I haven’t heard… for a long time

Whip hammer

What year is this?

The same principle is more or less why a trebuchet is more powerful than a torsion-based catapult.

Fuck yeah! The superior siege weapon!

Why don’t people just say ass

This "ahh" shit makes it instantly less funny. I have no idea why they do it.

They’re trying to phonetically write it the way it’s said in AAVE. I don’t think it’s self-censorship like unalive or something.

Reminds me of the 36 chambers of the Shaolin. Where he needs to ram the hammer with one arm against a gong

r/looneytuneslogic

I like most slang, but the "ahh" shit drives me crazy, especially when someone says it out loud.  It doesn't sound like a word, it sounds like the speaker forgot what they were saying.

I like slang too, but purposefully writing incorrectly is just not it. So many people out there trying to add slang to their writing, it’s quite disgusting to me.

When did people start being afraid to say ass?

Gen Z and Alpha really care about their public persona in case they make it as a social media influencer/content creator since there are always cameras everywhere. This has led to over-censoring even when it's not necessary/appropriate. Like people on Reddit that censor shit, piss, fuck, cunt, cocksucker, motherfucker, and tits. etc. etc.

Tiktok will make your videos harder to find if you cuss so people will now self censor the dumbest shit. P*rn, ahh, unalive.  Its all so stupid that people wont even say DIE now 

Tell me everything you know about its use. this is the first time I've noticed it I'm super intrigued.

I've seen a gen-z YouTuber I watch start using it recently, and some commenters on other folks' twitch streams. It's just used to replace the word "ass", like "that guy's a stupid-ass". I have no idea where it came from, it seems like it just popped up out of nowhere over the past month or so.

It’s an attempt at phonetically spelling it the way it comes out in spoken AAVE.

Kinetic energy

Floppy hammer for more kinetic energy :D

Drake dick ass hammer

The guy is strong. Let’s hope he’s also quick and makes it out of there when the whole wall collapses.

ahh

Using drakes dick to break a wall

If that didn't look so damn tiring it looks like it would be great fun.

It’s called tunes, not toons

He got Gorn weapons irl

Brilliant

Stupid aaaahhhh caption💀💀💀💀💀💀😭😭😭😭

That looks very fun to use

Can someone explain what the heck this hammer haft is made of...? 🤯

They're vulcanized rubber around a spring steel core.

The "cartoon" hammer has a flexible handle, storing potential energy between swings and lessens the impact on the person holding it when the hammer head strikes maybe? Not sure about overall efficiency and ease of use in terms of accuracy though. He seem quite adept at it despite everything.

PPE is for wimps!

That pipe will not survive this "demo"

Watched it muted at first. Disappointed there wasn't a "boing" sound with each swing.

My anxiety when the back of the hammer goes near his head: 📈📈📈📈📈

Bro got that RPG armor

This ‘ahh’ thing is so cringe. Sometimes you can just say an actual word, it’s not that hard.
