I had to use one for a full 8 hour day and it absolutely destroyed my ability to grip anything for like 2 more days. I went to the bar afterward and literally could not pick up and hold a 16 oz can of beer in my right hand.

From further upthread: LanceHunter posted:That looks a lot more insane if you think the barge is the aircraft carrier. Apparently the video was taken from the aircraft carrier. The boat that gets obliterated isn't the one being tested. It's just a (presumably unmanned) barge. The test ship is some distance away. EDIT: Oh, there was another page.

A man in Hiroshima was in the basement of a building 170 meters from ground zero and survived. If you have something between you and the shockwave it tends to help a lot.

To be clear, the recent video of the shock test did not involve any boats being obliterated and the video is from the ship being tested with people aboard who were fine despite being so close to the explosion. There's a little buoy like barge above a suspended exposive. https://www.youtube.com/watch?v=Qc-KC8RkREY The videos of ships being bombed with live weapons do, however, involve obliteration to some degree. glynnenstein fucked around with this message at 17:31 on Jun 22, 2021 |

Same thing if I use a palm sander for too long on a larger project. I don't do this stuff professionally, so I need to remember to take more frequent breaks.

Professionals aren't just unusually hardy. Everybody's body is a piece of poo poo. A vibrating tool has 'no code of ethics' or considerations for its own future. Use your brain. Use

We've got a rule of 20 on 5 off minimum for vibrating tools in the shop. The longer you go the more breaks you take. Like eventually it's 10 on 10 off.

I had a friend who rode a long bike race where the roads were poo poo. His hands got hosed from the handlebar’s vibrations and he couldn’t grip anything for DAYS.

I'm less worried using a grinder once a year than if I used it 40 hours a week. Like I don't (usually) use ear pro at concerts I go to a few times a year, but I would if I was a musician playing shows every day. Jet Jaguar posted:Yeah and not just tools! This is something I'm more concerned about! I need better bike gloves.

Uthor posted:... I have a set of plugs I wear to concerts, the kind for musicians where they're designed to dampen frequencies relatively evenly. Well worth it, imo, especially if you like death metal. One time I lost one, and by the end of the show my hearing was noticably worse on that side. That's a pretty clear sign the plugs are a good idea.

I have an invasive growth problem in my yard and surrounding properties and me and my neighbors deduced that the fastest and easiest way to cut down the huge vines from the tree trunks was to sawzall them right off.

This could be partly technique and equipment as well. I use a grinder a lot, if it's really shaking it usually means you've got an unbalanced disk, or you're not applying the right kind of downward pressure, or you're binding up in the cut, or you keep catching the edge of the piece and you get kickback. A good grinder with good wheels being used properly shouldn't be moving much more than it does running empty not touching anything. Which is still significant and can cause harm mind you but shouldn't cause major ill effects right away. Part of your hands hurting can also be from the effort of just holding it up and moving it around. I used a larger than normal grinder for almost two hours once and I was fine except my right elbow was on fire later that evening, just from the stress of holding it.

After a five week cross country motorcycle trip, I felt vibrations in my arms and hands for days and had a very difficult time with gripping things. The body is not meant to vibrate, but I never knew there was a name for that thing.

glynnenstein posted:To be clear, the recent video of the shock test did not involve any boats being obliterated and the video is from the ship being tested with people aboard who were fine despite being so close to the explosion. There's a little buoy like barge above a suspended exposive. It's a float, with the charge suspended some distance below. The float is a complete loss, naturally. The float, in turn, is being towed by an ocean tug. The test ship has workers with laser theodolites tracking the float, so they know the relative position. Sometimes, if they need very precise positioning for some reason, they'll set up a shot where the test ship is stationary, with the float positioned by a three point cable rig running to the bow and stern of the test ship, and the tug tensioning the third leg. As to how people could possibly survive that, they know how big the bomb is, and where it is, and keep it well outside the chunky salsa radius. They also know it's coming, and a ship wide announcement to "brace for shock" and a countdown. Hint: hold on to something solid, and don't lock your knees  Watch the John Paul Jones video.

Deck slap is an interesting way people can get hosed up in that you probably have never heard of https://pubmed.ncbi.nlm.nih.gov/25895417/ quote:'Deck-Slap' is an injury pattern first described at the Battle of Jutland; https://pubmed.ncbi.nlm.nih.gov/21808204/ quote:Anti-vehicle mines and improvised explosive devices remain the most prevalent threat to coalition troops operating in Iraq and Afghanistan. Detonation of these devices causes rapid deflection of the vehicle floor resulting in severe injuries to calcaneus. Anecdotally referred to as a "deck-slap" injury, there have been no studies evaluating the pattern of injury or the effect of these potentially devastating injuries since World War II. quote:Forty calcaneal fractures (30 patients) were identified in this study. Mean follow-up was 33.2 months. The median New Injury Severity Score was 17, with the lower extremity the most severely injured body region in 90% of cases. Nine (30%) had an associated spinal injury. The overall amputation rate was 45% (18/40); 11 limbs (28%) were amputated primarily, with a further 3 amputated on return to the United Kingdom. Four (10%) casualties required a delayed amputation for chronic pain (mean, 19.5 months). Of the 29 calcaneal fractures salvaged at the field hospital, wound infection developed in 11 (38%). At final follow-up, only 2 (6%) were able to return to full military duty with 23 (76%) only fit for sedentary work or unfit for any military duty.

LanceHunter posted:There has been a strain of thinking among some that surface vessels are deprecated and will all fair immediately the event of a large-scale, major-powers war. They can't really hide, and they can't outrun ICBMs, so if things were to ever get hot between the US and a country with a strong missile program then they'd all be sunk in the first day. I imagine tests like this are meant to counter that argument. It's not real life but a group of flight sim people using a fairly detailed air combat sim have been trying to blow up a us carrier in a full carrier group with whatever than can think of to see what works. It's pretty interesting to see just how absurd they have to get to clear (simulated) modern air defenses. https://m.youtube.com/playlist?list=PL3kOAM2N1YJdV_JwZaN1yGScRAb_yUTHx

"grim reapers" are incompetent morons in addition to being alt-right shitheads. Also, extremely  to anything related to ship damage modelling in DCS. It's a fun game, but ships are just blobs of hitpoints that works perfectly until they reach 0%.
