2023 United States Grand Prix - COTA, Oct 20 - 22

[Sevach]

I'm laughing at people writing "Russell was slower because he was running a legal car"

Imagine thinking that two teams decide to run their car illegally just to finish 2nd and 6th in a championship long finished! Setup has nothing to do with skid block wear! Skid blocks get worn out because of kerbs, bumps or going off track somewhere! Just like Schumacher at Spa 1994 after he spun! It was pure setup preference since Hamilton has been saying for a while that he wants to feel the rear end more!

After 2 Qualifying sessions and 2 races at a track so bumpy as COTA it was inevitable that some skid blocks might have been worn out! Had the FIA checked all the field I'm sure over half of the field would have been DSQed! Maybe Verstapen for example got away with it by going off the racing line down the straight in the last few laps, which looked strange to me but maybe it now makes sense! No one would want to get DSQed for such a reason...they just got unlucky!

Red Bull is just smarter with these things, what they did at Spa, lifting through Eau Rouge they play the margins to perfection.
Wouldn't surprise me if we learn that at select points of the race he was conserving his plank in various ways.

Hamilton knew the battle was with Ver, and a bit Nor. Everyone knew, even me. So ofc he goes out of his way to manoeuvre Max out of contention for an overtake. Max had a good start and already positioned himself on the outside. If Lewis kept a tighter corner Max would have had him. But it was funny to see indeed.

Sainz already had him, he recognized that and needed to focus on Verstappen.
Maybe Charles should've thought like that in the sprint.

Throttle works both ways. From piastri's view there is no risk, ocon is just slow over the bumps which allows piastri to get slightly ahead very early and he's ahead for a good 2-3 seconds before the crash, which ocon was perfectly able to avoid, had he not been solely fixated on beating gasly out of turn one. Another Ocon habit, nothing else matters except beating his teammate, thats why he doesnt even entertain the possibility of someone coming from the outside, its completely out of his mental capacity in that moment.

Dunno as well....
I mean, this video is intersting:
- It shows that Ham does not give a --- about the Ferraris. He was just making sure Verstappen is well outside the track even compromising the exit for this, he needed to steer to the ourside.
- It shows that Ocon is actually leaving much space on the outside for Gas. Remarkable, he could have also just gone for the apex there as Hamilton did.

I would put the crash into the "bad driving" category. Nothing more. Slam dunk penalty. Same topic as always.

Max is the devil for moving over on free air in the sprint.

Hamilton does his usual US GP T1 shove that he's done for years and crickets. He's full on the left side of the track defending on Sainz, and then swings to the opposite side to push Max off.

lets not be selective. max took many pages from schumis book on moves on track.
however lets look back at 2012 when radio comm broadcasting to the world was rising. merc was a tyre eater every race, but did we ever hear schumi go on a rant all the time complaining that his tyres were fukd? I think the only time we heard him swore that year was when he collided with senna in spain.

How much radio was available to the general public in Schumacher's 20's? Don't be ridiculous.

Mclaren and AMR is astounding. I have a pretty good idea what happened to AMR but how Mclaren did it is not totally clear to me.

Went in the wrong direction with the development late last season, realized sometime over the winter and corrected their path but it was too late for the launch spec. Launch car was essentially abandoned and it came as almost identical to the Singapore 2022 spec. They then focused on bringing the Austria/Silverstone package which should've been their launch spec

Similar with mercedes really - realized what they'd been doing was wrong at the very end of their 2023 development but was too late to launch anything but the w14 zeropod edition.. and the chassis compromises means that they couldn't salvage this year like McLaren have done & are focusing on the w15

We even knew of this being likely as early as the winter.. Stella etc not being optimistic about the launch spec. And news of issues with mercedes wind tunnel correlation and changing of development direction very late meaning the launch spec sidepods would not be around for long..

That's my interpretation anyway

Scarbs knowledge is lacking a little there. For a metal titanium is a poor thermal conductor. To show any appreciable temperature change you'd have to be bottomed out for a significant period of time (like when a car has a flat).

You don't need fast frequency response of the metal. You are just looking for the long-time temperature average. There is likely a good correlation between a colder skid block, and a higher ride height.

They have accelerometers to measure actual impacts.

My thinking was another way to do this is to embed conductive loops in the plank. (like a strain gauge). As the plank is worn, the output voltage changes. Could be a messy signal though. No idea. productive vehicles have a very rudimentary version of this in the brake pad wear sensors.

Since it's a poor conductor any heat generated from intermittent contact with the ground will not transfer to the sensor quickly. Not to mention as soon as it comes off the ground, the area that did heat up will cool back down to its base temperature quickly because of all the air flow.

good change anything that actually makes it to the sensor might not look like anything more than noise.

Titanium might not have the conductivity of copper, but it's still a metal. You are making it sound like it's a vacuum gap .

It's thermal conductivity is ~1/14th of aluminum, and ~1/23rd of copper. One of the reasons it's used in various industries like f1 is because it's such a poor conductor.

but it makes pretty sparks.....

and copper has 33 times the electrical conductivity of titanium. You still should not stick a titanium fork into an electrical outlet...

It's still a metal and compared to actual thermal insulators, it's going to conduct heat to a large degree. The temperature of a titanium skid will likely be good enough to give you rudimentary idea of how much skidding you are doing.
