That wasn't a particularly thick floor, apparently.
Seems like Tobi has reached new lows.
It's Lorg, I figure either the people paying for it or the guys that built it cut corners to save money. Just doesn't seem like the place that would have a building code.
And now!!! To see the hidden secert face of the construction yard's iron ball.
"I'm just doing my job, sir!"
- Wrecking Ball
Tobi's plans tend to fall through quite often.
DAMNITT BARRY I TOLD YOU NOT TO MAKE THE FLOORS OUT OF TISSUE PAPER
Well, Tobi doesn't seem to be on the ball anymore. Let's hope she isn't under the ball either.
Let's see, weight of wrecking balls... Smallest ones are around 450 kg, larger somewhere 5.4 tons. Taking falling height to account... well... how thick floor anyway must be to withstand force of whole thing?...
Someone contact XKCD!...
Hope that doesn't go all the way down to Whatshisface.
Reminds me of one trap I made for goblins in Dwarf Fortress, though it crashed through more than one floor. There were body parts left everywhere, never properly cleaned up.
Okay Grey, time for shitty, inprecise math!
I'll assume a 2000 kilo ball, as that makes it easy to solve, as well as a 10 meter drop (I'm lazy), and an impact front of 0.3 meter (wreckling balls are pretty inflexible).
E = (2000 kg)*(9.81 m/s2)*(10 m) / (0.3 m) = 654 kN
The yield point of concrete is about 4000 psi ~ 2800 N/cm^2
Assuming most of the force is concentrated on a 0,5x0,5 meter large area...
Okay, that roof is not made out of concrete, it's made out of tissuepaper and hopeful thinking.
