DrBouvenstein posted:You know, it might not be a bad idea to schedule an EKG with your doctor. There could be some underlying damage to your heart you don't know about, better to get on it now before it potentially becomes a problem later. Seconded. Heart problems can appear several days after an apparently harmless shock. Our yearly EHS training states that you should always have an ECG taken after a shock.

It seems to be common in the US, there are several chemistry videos on Youtube showing how to purify the stuff. The best chemistry channel: https://www.youtube.com/watch?v=BJx0GJSYxBE

Elsa posted:heavy truck brakes are usually designed to apply when the air pressure drops. You sure that's what's going on? Or is it some type of airport safety design that trucks have a brakes-off resting state. Only the parking/emergency brakes are the active-without-pressure kind. Service brakes (i.e., the normal ones controlled by the brake pedal) need air pressure to work.

EKDS5k posted:On trucks there is no difference. They run off the same air supply, and are the same brake pads. If the system loses main pressure for whatever reason then the brakes apply automatically, via a massive spring in the actuator. You need system pressure to release them. On any truck I've driven* that applied only to the parking brake, not the service brakes. * A grand total of maybe three different types, 30+ years ago.

McGavin posted:Jesus Christ, what do you need 6 kg of one of the strongest known neurotoxins with almost no applications for? No, seriously. John D. Clark posted:Phil Pomerantz, of BuWeps, wanted me to try dimethyl mercury, Hg(CH3)2, as a fuel. I suggested that it might be somewhat toxic and a bit dangerous to synthesize and handle, but he assured me that it was (a) very easy to put together, and (b) as harmless as mother's milk. John D. Clark posted:At NOTS, Dean Couch and D. G. Nyberg took over the job, and by March 1960 had completed their experiments. They used a 250- pound thrust RFNA-UDMH motor, and injected mercury through a tap in the chamber wall. And the thing did work. They used up to 31 volume percent of mercury in their runs, and found that at 20 percent they got a 40 percent increase in density impulse. (I had calculated 43.) As they were firing in the middle of the desert, they didn't bother with the scrubber. And they didn't poison a single rattlesnake. Technically, the system was a complete success. Practically—that was something else again. Source: https://library.sciencemadness.org/library/books/ignition.pdf

Afterwards he would have to connect the brake lines.

zedprime posted:I don't know, a risk analysis would probably say he could have control over the speed of the car by not standing in the line of fire of a moving car. It's apparently standard practice (I see it done regularly in the rail yard adjacent to the local station), but not at that speed.

Volcott posted:Not knowing leaving the scene after you've hit someone is illegal and not knowing you've hit someone, thus having no reason to do anything other than drive normally seem like two different things. I was a bit facetious, but a prosecutor would probably argue that if you don't notice you hit someone, you may have been distracted or not in full control of your vehicle.
