GD_American posted:I got to meet one of the guys that helped save the Samuel B; the mine had broken the keel and knocked its engines off mount, killing power at a crucial time. They basically got every come-along and chainfall they could find, connected at points across the break, and hinged the bottom of the ship back shut, which is mind-bogglingly That must've made the rebuild a piece of cake. Destroyers are pretty much designed like lego kits, if HMS Zubian is anything to go by.

MikeCrotch posted:The most OSHA thread event was probably Japanese aircraft carrier Taiho, which took a hit that cracked her aviation gas tanks and started filling the ship with gasoline vapour. This was obviously a problem so the damage control teams open up all the vents to get fresh air...which turned the atmosphere of the ship into the perfect ratio for a fuel air bomb, leading to the ship to explode and sink 6 1/2 hours later. Wikipedia posted:About 14:30 that afternoon, 6½ hours after the initial torpedo hit, Taihō was jolted by a severe explosion. A senior staff officer on the bridge saw the flight deck heave up, and the sides of the ship blew out. That thing exploded like a cartoon cigar.

Being an American sailor in the tropics in World War II was miserable; the ships were not designed to keep cool. Some sailors would sleep in hammocks along the edges of the ship, and whenever it made a turn, the hammock would be dangling out over the open ocean.

over 3 months, I learned that a second year physics student doesn't have much to contribute to poo poo outside of kind of just being a gopher for simple things, that I will never be qualified to operate heavy equipment, and that engineers really do try really goddamn hard to make sure that heavy equipment doesn't injure people, because the liability is extraordinary for this type of use case. Okay so there's this thing called a factor of safety in engineering. Basically like if this specific bolt model snaps at an average of 100 psi, you'll multiply that by like 70% for something dummy safe so they're rated for 70 psi. If they're for a doll house, you'd probably get like a 90 psi. Safety codes i don't know about, but the more dangerous a failure, the higher the factor of safety. This can be applied to designing structures (what's the max load we think this will take x >100% FOS), or load limits for bridges, trailers, and cranes. y'all are probably already plenty aware of what a factor of safety is A crane failing and tipping over can cause catastrophic amounts of damage and harm, so I don't know the exact number but their FOS is going to be very high. Like, if you told me it was like a factor of 2 (so max load 100lbs before tipping, it's only rated for 50lbs) or more I wouldn't be surprised. There's safety measures in places as far as foundation, boom angles, boom length, and those all go into a math equation to give you your rated load. you are literally handed a guidebook with these figures calculated ahead of time 0 To tip a crane you have to Be negligent in making sure the foundation is suitable And/or Be negligent in checking your maximum rated loads for your boom/angle And you have to be so loving negligent in this that you completely pass the factor of safety and hit the fail limit. And in the above picture, that's not a foundation failure, it's literally still propped on the road so they had to overload this poor crane past anything it was EVER rated to hold. osha really doesn't like cranes tipping if you were wondering

Okay yeah factor of safety looks like... I found a FOS of 5 quickly scanning the OSHA guidelines linked in a doc So if the fail load was calculated to be 100lbs, it'd be rated for 20lbs. 1926.753(e)(2) Potato Salad fucked around with this message at 03:25 on Mar 18, 2021 |

Aaaand then you get normalized deviance and your safety factor disappears. Machinery needs to be designed so that if you go above the published safe limit something expensive breaks and has to be repaired, so no-one can get uaed to exceeding the published limit with nothing going wrong and then they qccidentally hit the hard limit.

Chamale posted:Being an American sailor in the tropics in World War II was miserable; the ships were not designed to keep cool. Some sailors would sleep in hammocks along the edges of the ship, and whenever it made a turn, the hammock would be dangling out over the open ocean. Fun related fact:  This is an E-2 Hawkeye. It operates from aircraft carriers. Notice how much distance there is from the main landing gear back to the tail? Well to save space on the flight deck, it's common for them to be parked so that main gear is backed up right to the edge of the deck, with the tail hanging out over the water. Normally as part of the preflight walk around, one of the crew members is supposed to climb up on top of the fuselage to make sure everything is good. However, in a bit of good OSHA sense, this is prohibited if the tail is sticking out over the water. Instead you're supposed to just poke your head up out the top hatch and look around from there. Of course, it's not uncommon to think you're good, and get up there only to realize that it's covered in ice, or you're parked behind the jet blast of a jet that's about to take off, or any of the multitude of other ways a flight deck can try to kill you. The Lone Badger posted:Aaaand then you get normalized deviance and your safety factor disappears. I think this was mentioned in one of the Deviant Ollam elevator videos that's been posted here before. In most elevators if the penultimate safety stop triggers it will disable the entire elevator until a technician comes out to reset it, because that stop should never be hit unless there's something drastically wrong.
