RandomPauI posted:male to male extension cords? I mean, I know what they are but, why do they even exist? Because someone installed their Christmas lights backwards and was too lazy and stupid to redo it the proper way. TBH it wouldn't take that long to cut off the ends and swap them as long as you had a set of strippers and the right wire-nuts

Hubis posted:Interesting! That makes sense. Why are they still isolated from one another -- in case one of the paths is taken down for maintenance? They're not electrically isolated. AC current tends to want to propagate at the surface of a conductor, not the interior. This is called the skin effect. The depth of the conductor the current will travel through depends on the actual conductance and permeability of the material and the frequency of the current, but for 60Hz AC in copper it's something like a centimeter. So making a cable much thicker than that doesn't reduce the resistance very much at that frequency, since the current's only going to travel through the outer centimeter of wire; you'd be using a lot more copper to get a lower resistance. Instead, you use multiple parallel cables. quote:Japan Times posted: This sentence is literally nonsense. As in, it has no actual semantic content and is meaningless.

If you were at the Little Boy hypocenter, I'm not sure how many joules you'd have absorbed but it would have been enough to totally vaporize you so at least 127 megajoules or so.

It's a dumb thing to say, but they might have meant that if there wasn't a fireball incinerating him or a shockwave crushing him, that would have been the dose he would have received from ionizing radiation at ground zero. I'm pretty impressed that he survived so long from such a full-body dose. Enough of that 17 Sv would have been from neutrons that he was probably in the 5-10 Gy range of actual energy deposition but in that range the expected rest of your life is only around 30 days.

Instead, you use multiple parallel cables. Overhead power lines aren’t made of copper. They’re made of aluminum, which has more tensile strength and less weight for the same conductivity (but a larger cross section). Often there is a steel core.

I know this always turns into a derail between the safety ninnies and the realists, but wire-nuts are perfectly safe -- and code-legal -- when they are used in an appropriate location (i.e., not in a place with the possibility of water intrusion), installed correctly, and the correct size is used for the wires being connected. Granted, a ton of people use the wrong size or use them on a boat or don't twist them down correctly or whatever, but those things are user error, not any inherent problem with the device.

I'm not disagreeing with you, but I have to point out because I'm a giant sperg that "code legal" is the absolute bare minimum.

Didn't mean to convey that they were, just used copper as an example for skip depth because I have no recollection of what the value is in aluminum. BattleMaster posted:It's a dumb thing to say, but they might have meant that if there wasn't a fireball incinerating him or a shockwave crushing him, that would have been the dose he would have received from ionizing radiation at ground zero. Even if we're being charitable and they meant to say that, then they're still insanely lowballing the dose from an atomic bomb. Radiation dose if you were standing at the hypocenter would have been well in excess of 100 Gy. Phanatic fucked around with this message at 00:36 on Oct 26, 2017 |

I assume there was an impressive amount of speed to achieve that. Also a pretty good story for the unemployment line.

Also a pretty good story for the unemployment line. Forklifts aren't all that sharp, but like medieval longswords, sharpness is not paramount when you add enough speed and weight. Small-end forklifts still hit half a ton. 1,000 pounds moving at walking speed can drive that one tine through a steel beam no problem.

Yeah, if there's one thing I've learned from this thread it's that forklifts are accidentally designed to destroy anything they collide with. Deceptively high mass for their size and lots of torque to maneuver it around.

Broadswords were sharp though. They couldn't cut thru armor, but they'd go thru flesh and bone just fine.

RandomPauI posted:They must have some other purpose than that though, especially if people were running them in the attic for purposes. They were almost always hooked up to a light/fan installation. The only exception is in one of the McMansions, which had it plugged into a chandelier instead. The "it might be for generators" thing was a nice thought, but when I suggested that he scoffed at the idea. Unless your attic is EXTREMELY well ventilated, running a generator up there is a good way to fill the space with Carbon Monoxide (and then possibly fill your house with it as well). The m/m extension cords were just run of the mill extremely dangerous corner cutting, either due to laziness or stupidity.

Tangentially related to trucker OSHA: Is there a detailed breakdown of the startup sequence Charlize Theron uses to start the truck in Fury Road? Is it just a couple thermal circuit breakers and solenoids?
