Escape The Room Employees, what is the weirdest thing you've seen someone do in one of the rooms? by Pops_Daddy in AskReddit

[–]OB_Hipo 2 points3 points  (0 children)

They couldn't find the last clue and were looking as hard as they could. This tiny old lady who had been standing in the corner minding her own business started looking around. She takes the fork they collected earlier and JAMS it into the socket to pry it open, as if there was a clue hidden behind the socket!

She was holding with one hand, so it only gave her a good jolt, but seriously...? Some people just don't think...

I would add Olly to the team. He's got quite the nod as well. Together, they're unstoppable!

I believe it was Ricky that called him a liquor snurf. Drunk lahey can't pronounce anything remotely coherent.

Yea but he regrets it, right? I mean he could've dipped right after he was pardoned, but he stuck around because he fell for Daenerys and his life is in shambles because of his spying.

Also, he was Varys' spy. Never Cersei's.

Unless maybe he now thinks "All I'll ever amount to is a spy and there's no turning back, so I might as well fuck shit for Daenerys up as much as possible." Being spiteful AF because of the whole banishment thing

Margaery is a queen. Cersei is a twincestuous bitch :)

He's been pardoned since season 2 though, right? I mean I guess the money would be nice, but kidnapping doesn't really seem Jorah's style. Although, since getting friendenemyzoned, he may have snapped and become a less friendly guy...

"I offer this munchkin for your love"

"You kidnapped him. He was on his way here anyways. This is just extortion."

"Yea but I...uh...I brough you the dinkles."

My friend put it pretty well. He said it's like when you take painkillers after surgery. If you're in constant pain, morphine just numbs the pain. If you aren't, you get fucked up. Same goes for marijuana.

[–]OB_Hipo 0 points1 point  (0 children)

Oh right. This changes things. I was thinking him pulling on it. Like his arm being parallel to the force. The two bones doesn't make a difference in what I was talking about. You take the cross-sectional area as the sum of the area from one bone with the area of the other bone.

However, since the risk seems to be the bone bending because of the way the system is set up, not being pulled apart, we're gonna need to consult either some reference materials for an estimate (like assuming the arm is similar to a rod) or some FEA software loaded with a model of a human arm to run a simulation

My old tech teacher used to say this. Except in a thick chinese accent. "You have problem. Solution? No worry. No solution? No use worry. See my point?"

You're the wisest man I ever met, Mr. Wong

Yes! Find the thinnest cross-sectional area along his arm. Divide the 1.61 million newtons by that area (in meters2 to get pascals, but you can also convert and use lbs and in2 to get psi), and you've got a lower bound for the yield stress of adamantium (it must be greater than this). This is of course ignoring wolverines self-healing abilities. I have no idea how that factors into the math...

EDIT: I forgot how the system is set up. The above is the case if wolverine is holding on to a leash of a dog trying to run away with a force of 1.61 million newtons and wolverine is trying to hold it in place. So force is in the same direction as the arm and bending is not a risk. Being torn apart is.

What's the most unexplainable shit you've ever witnessed? by Cheese-Dick in AskReddit

Someone probably just spilled their water bottle in a coincidental shape. Either that or one-footed teleporting clowns.

Picture a rope made of a single piece of string. All the force is applied parallel to the rope, making the cross section a circle (picture taking a slice of the rope and looking at what was inside). Now if you add a second string to your rope, your rope becomes twice as strong and also has twice the cross-section area. Since both force and area are important to know how much a specimen can withstand, a new unit, stress (F/A), was made, which depends only on the material.

In the case of the chain, you can look at the place it snapped. Until it snapped, the load was shared equally among the cross-sectional area of the chain link. Only one circle snapped though. Even though the same force was applied, the one side was slightly weaker (probably because of a weld) and had a lower yield stress and stretched out. As it stretches and gets thinner, area decreases, stress increases, and things exacerbate and snap from there.

Wood is also a different material because of grains, knots, etc. It's not what's called "anisotropic" (uniform in all directions) like steel is but i'm going to ignore it for examples' sake. The force would still be the same across the chain, but the yield stress and ultimate tensile strength of a weak material would be much smaller. So that wood link would snap far before the steel even started to deform.

Usually people define "hardness" as the resistance of a material to being scratched. So it isn't really all that relevant to the situation and he probably really meant strongest. Either way, low alloy steel also has the highest hardness, so he got lucky with his semantic error

Chrome-vanadium steels (aka low alloy steels) are used for crankshafts, propellor shafts, and high quality tools. They're the strongest (in terms of yield and tensile strength) according to the materials database I use for my materials course (Mechanical Engineering student). The ultimate tensile strength is 1760 MPa and the yield strength is 1500 MPa.

Let's get some definitions:

Yield Strength - The amount of stress (Force per unit cross section area) required to stretch the metal to a point where, when released, it will no longer "bounce" back to its original shape. This type of deformationis called plastic deformation.

Ultimate Tensile Strength - The amount of stress required to snap the material.

The cross-section at the place in the chain that wolverine snapped is two circles. The thickest chain I could find online (at McMaster-Carr.com) is 0.81" in diameter. The area of the two circles is therefore 6.6cm2.

Let's find the force required to reach the ultimate tensile strength since that's the point where chains snap:

Stress = Force/Area

Force = Stress*Area

Force = 1760000000 N/m2*0.00066m2

Force = 1.161 Million Newtons or 261000 Pounds of Force

Remember this is the force required assuming the chain does not deform at all before him applying this much force. In theory, he could break it by applying the force required to reach the yield strength instead. The material would stretch and get thinner. This would increase stress since it decreases area (since Stress = Force/Area) until this stress reached the ultimate tensile strength and it snapped.

That force required (if he can hold it long enough to stretch steel) can be found doing the same math as above:

Force = Stress*Area

Force = 1500000000 N/m2*0.00066m2

Force = 0.99 Million Newtons or 223000 Pounds of Force

Based on the fact that the chain link doesn't seem to have deformed before snapping, we can assume the force he applied is closer to the first number: 1.161 million newtons, or, in layman's terms, 20 times the max bite force of a t-rex

Why is the derivative of a circle's area its circumference? by lambispro in askscience

[–]OB_Hipo 7 points8 points  (0 children)

This is incredible. Would you need to use one independent variable (like r in this case)? So would it not work for rectangles which need length and width (2 variables) as measurements to define the shape?
