dissss posted:Yeah there have been a few high profile incidents in China recently that illustrate the importance of school bus safety (in particular not overloading them) I don't know. Probably because that's the way it has always been done. Another thing is that they're all BoF and the axles are going to be so high because of the wheel diameter. Is the U.S. the only place that uses our sterotypical School Bus? If I see school kids in a movie from Britain, they're on a coach.

Everywhere else in the world I've been a bus is a bus - ones used for school aren't any different in design to any other. I think in most places legislation means buses must be accessible which essentially means low floors. This is a typical design

Hypnolobster posted:I've always sort of wondered why school busses don't have underride bars. A big reason as well I would assume is that they just wouldn't have the clearance needed in a lot of situations. Ever been behind one of these and seen the exhaust pipe squished near flat? The rear overhang on them is massive and they go a lot of places that coach style buses wouldn't be capable. When I went to high school the exit ramp onto the road was pretty steep and it wasn't uncommon for the back end of the bus to scrape when it pulled out. The only way to remedy that would be to move the rear axle further back which would come with its own set of disadvantages. And really, the majority of the times I've seen this happen is appears to be the fault of the person stuck under the bus. They are giant yellow bricks that do not normally travel very quickly, and very likely won't be out-braking anything else on the road. Most of these accidents seem to be people just not paying attention and slamming into these things while they are stopped, which could be avoided with a bit more situational awareness.

Or any situational awareness, really. It's an enormous yellow 12ft tall bus covered in flashing lights. "Accidentally" hitting a school bus is on the same level as "accidentally" having sex with a transvestite.

I've seen them installed on some buses (or maybe semi-trucks?) and they consist of some 2" angle irons that would probably be good for stopping someone on a bicycle or perhaps a motorcycle, but anything with any kind of mass would just slow down about 1/2 mph while it bent so it would accomplish nothing. Almost like they are there more for letting the driver know he is up against something because he's getting a bit of resistance when he backs up.

They don't look like much, but they will ruin your poo poo in a hurry.

Maybe the guy did domestic fridges and had a cylinder of isobutane (r600a which is in newer domestic fridges sometimes) leaking, maybe he has 'hychill' in there (R290 ie propane that some use as an R22 replacement) could be some weird freak thing with a contaminated HFC refrigerant, or a pile of leaking MAPP gas cylinders? Second case was definitely acetylene though. Seriously, gently caress vans if you're a fridgie, get a ute! Fo3 fucked around with this message at 14:18 on Dec 18, 2011 |

The Locator posted:The only wrecks I've seen that make school buses look flimsy involved train locomotives. Yeah, the reason they all look the same is that is basically the safest design. They do not gently caress around with bus safety as they have to keep the kids alive sans seatbelts. I wouldn't be surprised for the reason for the lack of dot bars is to punish people for hitting a school bus.

School bus vs vehicle crashes look pretty safe, because of that bigass frame all buses have. They look flimsy as gently caress in any rollover, though. The canopy just collapses sideways, every time. Edit: for whatever reason, that's not the image I wanted to post. Oh well, just google "bus rollover." Pretty scary. Queen_Combat fucked around with this message at 21:58 on Dec 18, 2011 |

How much more would it ACTUALLY cost to make the rust-prone components out of stainless steel instead?
|
# ? Dec 19, 2011 08:31 |

Many times the original amount in a lot of cases. Stainless doesn't have a lot of the desirable working and welding properties that plain steel has. "Why don't they make the airplane out of the material they make the black box out of?" is a similar level question. In a few parts you could use stainless, but mild is superior in quite a few ways.

Alereon posted:How much more would it ACTUALLY cost to make the rust-prone components out of stainless steel instead? The more pertinant question is: Why don't they rustproof COLLISION MITIGATION COMPONENTS better from the start? Think epoxy hot-dip or several cycles through a nonferrous metal plating bath (nickel?). Up to the point it fell off (hit a frost heave bump on a lovely road) I had no indication there was anything wrong. I even sat on the bumper within the last month or so. Hit a bump, heard a thud, and then a plastic-on-asphalt dragging noise (not sure if it was better or worse than the "my exhaust is dragging" noise.) and I pulled over. Right side had completely given way, and left side was held on by some plastic screwclips by the wheel, and some rust. I unscrewed it and yanked it free. Too bad somebody didn't tap my bumper in traffic or a parking lot. Coulda let their insurance buy me a new rear bumper beam. I had a new in the foam-sheet rear bumper cover from when someone backed into me in 2004 and slightly puckered the one corner of the bumper and smashed out a tail light. Their insurance paid for my body shop estimate, and I directly purchased the tail light, and bumper cover. I installed the tail light, and left the bumper cover for "warmer months" but decided that I might as well hang on to it because the pucker wasn't that big a deal, and I quite literally purchased the LAST Honda Civic Wagovan rear bumper cover in Honda's US parts inventory. I put the extra "labor" money into a timing belt/water pump/head gasket job. So this poor bumper cover has lived in my mom's basement for 7 years. Since I was up in that part of the state when it FELL OFF I stopped in and grabbed it. Any central PA goons with a garage want to let me rent it for an hour or two to swap it once the part hopefully arrives (it, too, could be the LAST ONE EVER.) All I have is a windy concrete parking lot... Unheated garage is perfectly fine, gently caress the wind. On an unrelated note, since the bumper is off, I can now peer up into the "frame" box-channel things, and WOOHOO no rust! for "Any single part of this car can be CARRIED WITHIN this car" vehicles. I'll post photos of the actual bumper rust carnage this week when its light out and above freezing... EDIT!

I'm aware that stainless isn't used because it's more expensive, but I'm interested in knowing how much it would actually add to the price of a vehicle. It seems obvious that the rust-prone components would be a small fraction of the vehicle's overall cost (with most of the cost going to the mechanical and electronic components), so even multiplying the cost of those steel components several times would result in a small increase as a percentage of the total cost.

Over on the Subaru Legacy International forum, there's a thread where a guy talks about his new breaker bar, and how he was using it a bit too literally. The best part is this response: Garrison posted:Gotta lay of the 'roids duder. I've had a couple of regular 1/2" to 3/8" adapters go before, but those were cheap-rear end ones made in China. I can't imagine getting enough force to break an impact socket. Sponge! posted:I loving HATE road salt. Rusted straight off... Just the bumper beam itself though, thankfully the mounting points are rock solid. Road salt sucks biblical amounts of rear end. My current car is missing a couple of bumper braces because they rusted and broke off, and the bottom part of my driver's side fender rusted through so badly that the force of me removing my headlight assembly caused it to snap.

Is that a 3/8" to 1/4" drive adapter? I have effortlessly broken one of those with a small socket wrench. No breaker bar or hulking roid rage needed, 1/4" is some weakass poo poo.

The worst is when the road salt fucks up the captured nuts inside the frame rails/unibody. Holy poo poo does that escalate the level of repair quickly.

Alereon posted:It seems obvious that the rust-prone components would be a small fraction of the vehicle's overall cost The "rust-prone" components (unibody, fasteners, panels) are actually a huge cost of a car. And stainless does not work for certain parts of the car due to it's stress and toughness profiles compared to other metals. Did you even read my post? Anywhoo, something along the lines of a plating (though, you have to be careful there - embrittlement for certain ones) or coating would work better.
