BlackMK4 posted:I think you mean they effectively are the suspension They make up a critical part of it, but they do have springs and dampers as well in those cars. In Indy it's one of the open development areas, and obviously that's the case in F1 as well (as is most everything in the car)

I like the slow mo when they ride the inside curb out of a corner, and you can see the tire oscillating left and right. And speaking of open wheel racing, no one is mad about halos in F1 after today.

iospace posted:But seriously, if you ever want a demonstration of why tires for racing generally have thick sidewalls, watch open wheel racing. It's much more obvious on those cars than closed wheel: The only reason F1 still uses 13” wheels is because of resistance to change (and originally, a desire to keep brake disk size down). LMP cars use 18” wheels with small sidewalls and use the actual suspension to be the suspension. But since F1 is still saddled with those ridiculous high profile tires they have to deal with sidewall flex. Anything else is post-hoc justification. If 13” wheels and huge profile tires were actually an advantage you’d have seen them used at places like Pikes Peak or Time Attack where there are very few rules. drgitlin fucked around with this message at 19:57 on Aug 26, 2018 |

Yeah that is actually a hindrance as the tire flex is undamped and ideally you want the tires to be significantly stiffer than the actual springs and not part of the suspension. F1 cars have like those mass damper inerter things to try to deal with it.

Yeah, that. Nice to see proactive safety measures get real world validation. Usually something bad happens and then people worry about how to stop it.

They've been looking for solutions since Massa got brained by a flying spring, and Bianchi got brained by a caterpillar. It probably wouldn't have saved Bianchi, as his crash sheered the top half of the car off anyways. Massa: https://www.youtube.com/watch?v=IzKc76-isOk

Powershift posted:It isn't proactive. They've been looking for solutions since Massa got brained by a flying spring, and Bianchi got brained by a caterpillar. The Halo isn’t designed to prevent an accident like Massa’s; they added a zylon strip to the helmet to protect the drivers from small debris like that. Bianchi (and Dan Wheldon) were both cases where nothing would have prevented what happened, other than closed cockpit cars. But accidents like Henry Surtees’ or Justin Wilson’s would have been mitigated by the Halo.

david_a posted:Holy poo poo the responses to the article and some of the linked tweets The weird thing I see in this debate is that most safety items in sports tend to make people push the limits further. You can punch a lot harder with boxing gloves on, you can tackle or slam with way more force in full football/hockey pads, you can throw a harder pitch because the catcher is wearing pads and a mask If they want the sport to keep pushing the limits of speed and performance, they need to keep the drivers confident that they won't get mangled on the track through no fault of their own

All the good ol' boys thought it was for wimps, and then three or four of them popped like rock-em-sock-em-robots (Dale Sr., Adam Petty, and one or two other guys what weren't part of dynasties from the beginning of NASCAR) in a year, and everybody left alive and the sanctioning body realized "hey, this might be a good idea."

Really though, both of those boats should probably be on top of the scooter/car trailer.

This setup is legal in something like 30 states (I looked it up after seeing something like this on I90 outside of Chicago) except for the 3rd trailer hooked up to the payload and not the trailer itself. I mean, if the kia falls off you've probably got bigger problems.. but try this with something heavier and find out if the trailer-to-car hold down system can stand constant push/pull forces.

SeaGoatSupreme posted:The Nissan rogue, which has a cvt, has a manual mode for "sports shifting" I think automatics are required by regulation (or if not, then everyone agrees it's a good idea) to have some kind of manual control for towing and hills, i.e. the "L", "1" and "2" settings on your old 4AT that you never use and occasionally shift into accidentally. Once you have that then you may as well just add 3 or 4 more steps and sell it as a feature.

F1 cars have like those mass damper inerter things to try to deal with it. They used to, but mass dampers in F1 have been banned quite a few years ago. There is speculation that some teams managed to get a similar effect going through super-complex interconnected hydraulic suspensions (both when FRIC was allowed as well as afterwards, see Mercedes front suspension). Thing is that the tyres are a huge part of F1 suspension work, thus teams don't want bigger rims (which are coming anyway) because years of research go down the drain. Heck, they actually have passive systems in place that warm up different parts of the tyre (especially sidewall) by transfering heat from the brake disc over the rim to the tyre to achieve different suspension/side wall stiffness characteristics on different turn speeds. It's actually pretty insane how they managed to work the tyres into the overall suspension nowadays.

In fairness, if you made them run with a larger diameter wheel, they'd spend enough money to get up to speed with it pretty quickly.
