Then part of me wondered how much its a case of the lift is there to raise barges over the dam, and the dam is there to just power the lift.

Splizwarf posted:I know appearance and functionality are often not hand-in-hand, but it really looks made of silver-spraybombed cardboard. Yeah, but does it have functionality at all? There's a space frame underneath it that actually does all the structural poo poo. CF is only really useful in monocoque structures, isn't it? Other than the spoiler and splitter (which don't look that bad), that's all "cosmetic", in that GF makes an aerodynamic fairing just as well for a lot less time, cost and effort. Or he could rip all the other poo poo off and drive it like an Ariel Atom.

jamal posted:It's a good way to make light and stiff surfaces that see high aerodynamic loads. He would definitely be better off driving it with less giant wings on the car though. Generally you want to get the drivetrain and chassis/suspension dialed in before throwing huge aero loads into the mix. From a basics standpoint, it has a big splitter and big wing and such so there will be a reasonable amount of downforce. But there is no way of knowing how that downforce will be applied and what will happen at speed. If I had to guess, very pitch sensitive and unpredictable. Well, sure, those body fairings would see fairly high aerodynamic loads at M>0.5, but at car speeds I would have thought regular old fibreglass could do the job about as well. Those panels have small surface area, are not intended to generate much lift, lots of mounting points to the frame, not much bending moment... why would you bother with CF? (I say that not having done any CFD analysis on a car before). I'm sure the larger airfoils need to be CF, but he looks like he made those properly. edit: But yeah, perhaps he should have spent those 6 hours of testing on the drivetrain before worrying about aerodynamics.

jammyozzy posted:Nobody wants to build a heavy race car, especially at an event where your engine loses power as you go. The other problem you have is that the panels sit relatively high where you especially don't want the weight, so there's all the more reason to choose CF. I'm not saying you can't make a very light shell from fibre glass, but it's much easier if you start with something less dense. You're right. Money-no-object, CF will be lighter and I guess those few fractions of a pound matter at the pointy end of the racing industry. jammyozzy posted:The final reason is gently caress sanding fibre glass, that poo poo loving sucks. But you've never worked with CF, have you? silicon fiber is recognised as a foreign body, but carbon fiber is biologically inert. So silicon fibers get coated in little cyst thingies so the sharp silicon fibers can't cut/damage your cells, where sharp carbon fibers don't get coated and continue to cause cell damage for the rest of your (reduced) life. Very bad in the delicate tissue in your lungs when you breath them in

Grumbletron 4000 posted:I'm amazed at how little it takes to total a car these days. A couple of weeks ago my buddy banged up his SRT-4. Worn tires + rain + whatever unholy amount of power that thing is making now = making love to a guardrail. No mechanical damage whatsoever. Just a banged up front fender and a nice deep scrape across the doors and back fender. Even though those cars seem to hold their value well its very much totaled. I've been trying to convince him to buy it back and swap the engine into a K-car. We don't get that anymore in our part of the world. The government eliminated "repairable write-off" so now a car must be one or the other. Insurance companies will repair damage right up to the value of the car. It sucks when you're looking to sell and have a well timed accident, and it also pushes everyones insurance price up, but it does stop/slow backyard chop-shops and re-birthing.

You Am I posted:You'd think that, especially with some of the dealer charges that get slapped on cars. I remember one Australian car magazine doing an investigation into what the dealerships do for them to charge you close to thousand dollars, and all it ended up with at most dealerships was a $1000 car wash. I think it's about $600 for the car wash and $400 to remove the plastic wrap on the seats and interior.

Cakefool posted:Any goons here that work in aircraft maintenance? I attended a little talk at work a couple of weeks ago that talked about how the designers took "maintenance" and "what is humanly possible" and no part exists in isolation" into account when designing systems, fastenings, plumbing, routing etc. It was all very interesting & they showed some cad walkthroughs of an engine mounted on a wing, maintenance doors opening, human arm and recommended tool comes into view, bolts & brackets get removed, parts come out & in again. See if you can find the 777 anti collision light example. The 777 was designed from scratch on CAD and they did include a little human figure to see where arms can reach and what can be accessed with what range of motion and what physical strength and so on. They still managed to build the dorsal (or maybe tail) strobe light so the bulb could only be access from inside the dome but outside the pressure hull - so you'd better hope the thing lasts 20-odd years because there is literally no way of accessing it. I think there was something similar with the 787. The system exists but it isn't fool-proof. (They ended up doing an absurdly expensive retrofit to access it, but after the production line was in full swing)

Nidhg00670000 posted:vvv --- Well, I'd prefer if they'd just pipe the exhaust into the cabin, thereby solving the problem in another way, but if they added NOS they wouldn't be "rolling coal" because all that extra fuel (that comes out as black smoke) would be burned instead, giving MORE POWA and less soot. True, they wouldn't be dicks who "roll coal", but they'd still be dicks. So I say you shouldn't (unwittingly) encourage them. Unrelated fact: The best way to really piss off 'dem fag tree huggers is to prove that global warming is total LIEberal bullshit by piping your exhaust directly into your cab.

Craptacular posted:Somebody tell me why F1 (and Indy cars for that matter) still run open cockpits. Wouldn't an enclosed cockpit be safer? Is it just tradition and so they just deal with it being less safe, or is an open cockpit actually safer somehow? An enclosed cockpit won't save you if you're hit by a full wheel @ 300+kph. Nothing will save you. However, an open cockpit is easier to get out of in a fire, and making an enclosed cockpit that is as easy to escape from would probably be very heavy. I suspect it ultimately comes down to the lightest solution that meets the safety requirements of minimum evacuation time.

But yeah, sitting with legs raised to chest height, hand holds above shoulder height and bum down low at the bottom of the car can't be easy to get out of without help.

From a driver safety point of view, it wouldn't matter what damage you did to the car getting out. I'm guessing but it might be in the event of a breakdown; the driver gets out and over the barriers and the marshals need to move the car out of the way, so having a steering wheel easily re-attached might help?

Do you guys expect them to be like a petrol, or something? Everyone else seems to have cottoned on to how great they are and always have been. diesel != diesel. Different markets formulate diesel differently. Euro diesel is nicely refined and works well in cars, Aus diesel has more sulfur compounds and is generally poo poo in euro diesel cars, China diesel is not much better than bunker oil and will ruin a delicate euro diesel car engine and so on. It could also be that Americans on average don't understand that there will be differences with petrol, but delicate, efficient, clean diesel cars outside the EU are generally poo poo due to the fuel being poo poo.

His daily partner for so long. His friend, his companion, his rock. This is the vehicle that helped put his kids through college, put a down payment on a house and financed that new pool that Frank down the street is so jealous of. Then they begin strapping him into a chair clockwork orange style and force him to watch as the vehicle is stripped and then crushed in front of him. As tears of sadness run down his face, they unstrap him from the chair, hand him his final paycheck and wish him a happy retirement. Pretty sure they make a cheap watch out of the scraps which he's forced to wear to remind him of the impermanence and futility of existence for the remainder of his days too.

From a marketing perspective, the environmental protection mentioned isn't there to make greenies feel good, it's there to make board members not violate EPA rules. So it's actually much more effective than you give credit because he's speaking to the operations managers who are responsible for the mine revenue to tell them how easy it was to get back online, and also the chief internal salesmen, and to the board who don't want to get sued out their rear end for breaking environmental laws and are also decision makers who write the cheques.

fridge corn posted:i think commercial aircraft components have to adhere to international standards so chinese made engines will have to pass all the same tests any other manufacturer's They no-poo poo make two versions of their aircraft; One that complies with the rules and can fly outside China, and a domestic version that doesn't and can't. There's no reason this'll be any different. The main difference between the two aircraft is part tracking and log books. Domestic aircraft will fly until they break, foreign ones are supposed to have parts swapped out before then, but that's assuming the engineers actually did the work to calculate the service life, and having dealt with Chinese engineers, I highly doubt they did. I also guarantee that parts with unknown history or exceeded allowable service life will find their way into the foreign aircraft when a contractor somewhere decides to cut costs for a quick buck before going bankrupt and reopening in the same factory with a different name. tldr; don't fly on a Chinese built aircraft
