VikingSkull posted:More or less, yeah. The more it gets sideways, the more aerodynamic force is applied to the car to prevent it from getting sideways. The 80's were the heyday for this type of car, it's fairly rare to see it nowadays. They actually had sanctioned race series that allowed sideboard usage. If this is the case, then why does the sideboard go down nearly the entire length of the car? There's a reason planes only have the rudder at the back - in the front it actually makes side-slip problems worse, in the center it adds no torque. Only a rear-mounted vertical stabilizer works, and the further back, the better (because it can be smaller, and create less drag/weigh less). My best guest would be because when it does go sideways, it creates a huge force towards the inside of the turn to help with turning, instead of causing the car to straighten out and head right at the wall, like what happens when the tires start to grip again when counter-steering. In fact, since that thing doesn't seem to be balanced to have the center of pressure aft of the CG, I'd bet the "helps move the car into the turn" is actually what they're aiming for. When turning left, the results are the same as a vertical stabilizer - gets the car moving where you're aiming it, by creating a thrust force in that direction, and a drag force against the side-slip direction.

One thing to note: a plane yaws around its aerodynamic center. A car, however, has its front end anchored by the front wheels, so in the case of the sprint car, everything behind the front axle would swing to the right, and the sideboard would be pushed back to the left along its entire length - no counter-force back to the outside to destabilize things. Drag and mass of the board really aren't concerns either, since the aero benefit of a larger surface far outweighs those negatives for a ground vehicle.

Drag and mass of the board really aren't concerns either, since the aero benefit of a larger surface far outweighs those negatives for a ground vehicle. Aerodynamic forces should still act around the center of pressure, regardless of being anchored to the ground. If, for instance, you had a vertical stabilizer on the front, it would still create a force into the direction of rotation for the front, coupled with the rear trying to rotate out. Best case scenario, it makes no difference because the front tires kept it anchored. Worst case, it makes it worse. Which is probably why F1 and LMP cars have their vertical stabs set up so their CP is rearward of the CG (more effective than an entire sideboard when the purpose is keeping the car from yawing on straights.)

DixielandDelight posted:Was he trying to pass him? Sort of. They were essentially working in tandem to get closer to the car that was in front of both of them. The end goal would be for the drafter to pass the draftee, but this move was designed to get both of them closer to that front car. The drafter couldn't go as fast if he wasn't drafting The draftee couldn't go as fast if wasn't getting pushed by the drafter With a common goal in mind, they made a gentleman's agreement at 180mph to team up to gain ground on the car up the road End result: they both got closer to the guy in front, and they can battle it out to see who wins from there. This is all conjecture based on my bike racing experience, but I think it's reasonable logic.

What were they putting up a roadblock for, anyway?

You're joking, right? Literally every one of those riders in that video could have been written up for some kind of moving violation; people riding on hard shoulders, cutting solid lines...the list goes on and on, and this is even before we get to fleeing a police roadblock. Also, unless you have made arrangements with the police for escort (which I'm probably safe to say, they didn't), a mass ride like that should stick to one or two lanes only, not blocking an entire highway. Christ, even when the Angels ride into town, they ride two-abreast in one lane only - if a quasi-legal motorcycle gang can do it, why can't these morons? I hope every one of those riders gets the book thrown at them.

MrChips posted:You're joking, right? I know they're not going to include footage of them arsing around, but I really don't see anything that'd cause me concern until the roadblock avoidance nonsense starts. They might be breaking the letter of the law, but they're travelling at sensible speed and aren't popping wheelies every thirty seconds or swerving around, so I'm more inclined towards keeping an eye on them to ensure things continue like that.

Crossposting from what did you do to your car today thread. Truck got the transmission rebuilt for a second time. This time, the old guy at the shop did the rebuild instead of the young guy Old transmisson rebuild (solenoid sticking in the valvebody somewhere made it shift far too early, and it wouldn't downshift into 2nd past ~35mph) https://www.youtube.com/watch?v=KfPKRgl3YH0 New rebuild! https://www.youtube.com/watch?v=mHhvv09XCVc It's a 3/4 ton, 4.10 gear, big block, and still has the old horrifying energy crisis intake and (probably) cams. New intake and cams are going in whenever we get around to it. It needs a new speedo gear, too. The giant rear tire means that 65 is more like 60, and 70 is more like 63.

You probably don't see any other traffic around, because these dopes are blocking all four lanes of the highway, so there is no way for any other traffic to be in the camera view.

Not to mention the rubber layer that's between the outer tire layer and inner steel hoop and bolted to the inner wheel is going to wear out from all the flexing. Also "part of the car and not something you'll need to replace." Uh...there are a lot of parts of a car that can need replacing, some pretty regularly.

Driving on anything other than a perfectly manicured highway will spell the end for those steel rings. In a conventional tire, the air and sidewall can stand a bit of deformation when hitting an object at speed; raised manhole cover, square edged pothole, debris. This seems like it would transfer right through the solid rubber tread and mangle the rings / snap the 'spokes'.
