https://i.imgur.com/1MsDpzc.mp4 "I recently moved, and being the person I am, I made sure to meet the neighbors on either side of me. Both of them are elderly widows. I befriended them both and started doing small tasks here and there to help them because I’m nice. In turn, they allow me to borrow their late husband’s miscellaneous tools (i.e., weedwacker, chainsaw, etc.) if I need them. One day I borrowed an electric hedge trimmers from “Neighbor A” to do some landscaping on my own yard. When I went back to return them, I saw her own shrubs were considerably unmanaged and overgrown, so I wanted to tidy them up for her. I plugged the trimmers into her outdoor outlet, but nothing happened. I returned with a volt meter to test power. Nothing. I knocked on the door to tell her. She said, “Oh, that outlet hasn’t been working in years. I don’t know why.” I immediately knew what my next project was going to be. After a trip to the hardware store and a little bit of my own time, she now has a properly grounded, sealed, and protected weather resistant GFCI outlet! She thanked me with a blueberry muffin  "

Potato Salad posted:holy poo poo, around when and where was this? August 5 1998 in Walden, Ontario. Not much to be found in way of pictures because this was in the early days of the Internet being a thing but the explosion led to a lot of safety regulations being reviewed. 18000kg of ammonium nitrate explosive went up in that blast. Fortunately it was in the middle of nowhere or it could have killed a lot of people. EDIT: holy gently caress while trying to find pics I came across a PDF about explosion accidents and apparently chunks of that truck flew 2.4 kilometers. https://www.cdc.gov/niosh/mining/userfiles/works/pdfs/arorai.pdf EvilJoven fucked around with this message at 03:45 on Mar 16, 2021 |

We had a truck carrying 50 tons go up in 2014. Took out two bridges. Again no fatalities, because when a truck of ammonium nitrate is going up you loving leg it.

Samuel L. Hacksaw posted:Much worse, a bullet or series of bullets is just a micrometeor impact. The station is designed to take those kind of hits. Not from the inside. There's a micrometeorite shield on the outside that protects against hyper velocity impact by having a very thin film that makes the object fragment into very tiny pieces, so that the force of the impact is spread out over a much much larger area. A bullet coming from inside the spacecraft would probably make a significant hole but as someone else pointed out, they have patch kits for exactly that reason. Incidentally, this is also why anyting battery powered on the space station is modified to be powered by AA batteries or equivalent, because they are the ones that are least likely to explode and cause an issue on the spacecraft.

Typical weight restriction to tractor-trailers is 40 tons. Minus the truck and trailer, maybe 28 tons of cargo before you start getting into needing oversized/overweight permits. This is a basic US DOT restriction, states can and do get tighter depending on the bridge. But 50k pounds of AN is nothing to sneeze at either. For actual contribution, the Crescent City chemical fire/explosion from 1970 in Crescent City, IL. https://www.youtube.com/watch?v=292XmN5LUAM Story here: https://www.firehouse.com/home/article/10467137/crescent-city-train-derailment-40-years-later I grew up in the area, at one point a few miles away. It's a weird little town that's basically just a highway junction and the county fairgrounds some 3~ miles away. I was still 12 years from being born when this happened, but it's practically county legend and everyone local knows about it. CRUSTY MINGE fucked around with this message at 04:24 on Mar 16, 2021 |

A bullet coming from inside the spacecraft would probably make a significant hole but as someone else pointed out, they have patch kits for exactly that reason. The Micrometorite shielding on the ISS isn't exactly a "very thin film" quote:The US segment modules consist of an inner layer made from 1.5–5.0 cm-thick (0.59–1.97 in) aluminium, a 10 cm-thick (3.9 in) intermediate layers of Kevlar and Nextel,[351] and an outer layer of stainless steel, which causes objects to shatter into a cloud before hitting the hull, thereby spreading the energy of impact. On the ROS, a carbon fibre reinforced polymer honeycomb screen is spaced from the hull, an aluminium honeycomb screen is spaced from that, with a screen-vacuum thermal insulation covering, and glass cloth over the top. This is mostly relevant because the shielding on the US segment is a version of the Whipple Shield, which is just fun to say. Try it. Whipple Shield.

The Lone Badger posted:This one was 50 metric tonnes. Ah, Australia, that makes a lot more sense. I glanced over the article, but didn't see if it was a truck-train style. 50k kilos (I forgot metric tons are 1000 kilo, not 2000), poo poo, that's like 3 full tankers, unless you guys build singles that big down there. That much AN moving in one truck wouldn't happen in the states. It goes by train in those weights all the time though. CRUSTY MINGE fucked around with this message at 04:31 on Mar 16, 2021 |

starkebn posted:not sure what's going on in this one Dumbass didn't turn off the breaker, shorted the wires with the scissors. Just a light tickle at first before diving in for seconds. There are tools made to work on live wires with heavy insulation on the grips. Wouldn't have stopped this idiot from shorting it the way he was cutting. E: those are needle nose pliers, not scissors, my bad.

This reminded me of when my very strange autistic brother used a pair of scissors on some wires in the garage when he was 8 or so. Fortunately, like the man in the video, the rubber saved him. I'm not sure how he has been so lucky since then.

I think it blew the fuse, there was (still is) a nice notch melted out of the blade.

I did the same with a 12v/1000w power supply once. So capable of sourcing around 80 amps. And it sure did source those amps and it blasted a pair of nice semicircular holes into the wire cutters I was using.

I have a vague impression of getting to do this once or twice back in the very early 80s, or maybe I’m just remembering remembering doing it.
