deadlifting on second story floor. RIP?

[maccaz]

Anyone have home gym on second level of a house?

Prob should of thought about it before doing it but realistically will be deadlifting 200+ by end of year on second floor wooden carpeted floor.

Is it going to fall through (along with me) ?

Have rubber mats under the plates as well

Don't ever drop shit

Assume houses can support 200kg fat cunts so shouldn't be a Prob?

Cbf moving rack etc to garage cos then I gotta park on the street and that's far too much hassle

[Realtalk]

Just lights bro... Up at all seasons in howick I drop my deadlift and smash the lights out in reception underneath lol that's y left there they always on my case, wankers.

Probably stay away from the balcony if you're in West Auckland.

I would try and get something to spread the load. The problem isn't the 200kg - it's the sudden impact of 200kg with two very small footprints.

See this for reference:

I wouldn't do it personally unless you know your house is held up by steel beams lol. When you dropping that weight, the momentum and inertia means the shock is a lot more than just 200kg.

[teamfatboy]

I'd get used to parking on the street..

Shock is one thing, in a wooden-framed std kiwi house you'd expect to feel that throughout the place.

even if you put down a couple of sheets of 18mm MDF or 12mm ply to spread the load, whatever you stand on has to hold both your weight and the bar, so not just the 200 but more like 275+, through your feet. Then the load turns into two loads of 100kg, each in a very small area.

if you find drop it from maybe knee height, likeLeeroid said it'll have the same effect as a much heavier static load.  Best case you punch a hole in the flooring, worst case you break a floor joist...neither's a cheap fix.

I would deadlifts in the garage would be safer 

[jimmybro1]

Pseudo is right. Since the plate on the barbell have such small surface area for its payload the pressure is rather significant (N/m2). 

I would doubt a wooden floor of a house could withstand the pressure unless the plates are on top of cross members in the floor. 

If your not wanting to move to the garage prehaps rip up the floor and throw and few extra cross sections in to increase the stiffness of the floor. Matts will help to distribute the load and adsorb some of the force but would still pay it safe.

The force will still be 200kg on force (200kgx9.81m/s-2) its the pressure and impulse that will damage the floor.

Sorry bout it haha

 

Not too clued up on physics

Disssss Gui ay....... Knows more bout dropping weights than lifting them lol

LOLOL

[crazyfacials]

Ha, finally my mechanics paper can be put to use! the shear force you would exert would most likely be too much for your support beams to handle, jimmy is right on f=mg, long story short, only do it if you want to kill the people below you

[Realtalk]

Yeah like you gay dog Maccas, post pic of your dog for everyone on forum to see. LOL

Gotta lift them to drop them bro!

What's the terminal velocity of a falling 200kg barbell, Jimmybro?

[jimmybro1]

What's the terminal velocity of a falling 200kg barbell, Jimmybro?

Depends on the surface area of the barbell and plates. Terminal velocity is when the drag and gravitational force balance and the barbells frame of reference is no longer accelerating. 

Could do some quick back of envelope calculations haha. 

[jimmybro1]

Ok out of shear boredom a calculated the terminal velocity of a barbell with 220kg of weight rather than 200kg as five plates per side simplified assumptions and calculations. 

Using my trusty engineering bible the drag cofficient of a cylinder with reynolds numbers in the turbulent ranges the drag cofficient would be approrimately 1.0 based on the frontal area of the barbell will give a terminal velocity of 134.9m/s or 485.67 km/hr. 

[Pseudonym]

Hahaha! You engineers are all the same. I knew you couldn't resist!

That is gold. We should turn that into a tshirt - "Don't drop your weights. They can reach speeds of 485km/hr."
