Make NO excuses!! This stuff is the leading edge of human design creativity. Between F1, MotoGP, LeMans and WRC, Motorsport is one of humanities most innovative drivers. How someone wouldn’t find these parts interesting baffles me….
Looks like the strain gauges are mounted in a full Wheatstone bridge configuration. This means that (is homogeneous, isotropic materials at least) only axial load will excite the voltage measurement, so you theoretically measure only axial loads, and thermal strains should be cancelled out as well. For a composite like this, you would still be measuring some amount of non-axial load, though I would suggest each sensor would be independently calibrated in an Instron machine. I have done a similar setup previously on carbon suspensions and also carbon driveahafts to measure drive torque.
The strain sensors are typically resistive and put in a whetstone bridge (like a brigde rectifier as you mentioned). Then supplied with a regulated voltage on the top and bottom of the bridge. Then the signal is output on the sides of the bridge. Great content, thanks for sharing.
The reason that the front half of the wishbone has the flexure joint is because it is under tension during braking. The rear half is under compression during braking. Its very difficult to design a flexure joint that can flex, but not buckle under significant compressive loads.
The tether cable was introduced after an accident at Monza, where gilles villeneuve had one of this front tyres fly off. The wheel continued bouncing and rolling very fast. It ended up killing a Marshall after bouncing over the barrier. It was mid 90's, can't remember if he was at William's or BAR at this moment. This device proved effective quite a few times since. By the way, you titanium part are gorgeous, hats off to the machinist of the time 👏 Stress sensors, impressive too.
And dem brakes be hitting like 1200f or #null degree C. Sorry, 'mericn, I am currently installing counter tops Ain't gonna do the convert sorry. Don't want counters all cattywompus.
Tbh if you can go to the direction of Munro Live - you could still make a buck doing these videos. It still obviously requires some commitment and vision but I see it is well possible.
What a treasure you're showing us, stereo or mono matters not at all.
We thank you kindly, sir.

Thanks for that, great comment and one I was hoping for!

Ozzy, Thanks for that. Great comment. As mentioned before, my knowledge of electronics = dangerous in critical situations haha! All the best, Brian,
Very cool stuff.
29:28 thats awesome, using your control arms as a leaf spring, less suspension you need in your car also, expensive and wasteful though

Correct! However, currently they figured it out and run two flexures.
Omg Amazing pieces😳 , thanks for post it🏆👏
Thank you! A great video again! My bottom jaw is on the floor with all these details.

Keep up the great work. 👍
Thank you. 🙏
Oh great I was looking forward to the next one, back at sea just now so can’t watch it just yet👍👍
Stay safe out there Mike!
@@EngineeredtoWin Thanks Brian
Very interested, thanks for sharing
Ahhhh I see.....there's a temp sensors because carbon fibers limit is like 400 degrees fahrenheit
And dem brakes be hitting like 1200f or #null degree C.
Sorry, 'mericn, I am currently installing counter tops
Ain't gonna do the convert sorry.
Don't want counters all cattywompus.
Great video - thanks!
Wow....just wow
Thanks.
I didn't expect to see that flex joint in F1. Looks too primitive to be F1 part.
Volumes a bit better on this video.
Well chuffed you've another video up.
Bladed sway bar would have been the inspiration for the wishbone.
3 outboard connectors wheel speed, brake temperature and brake pressure
It is interesting to think about carbon fiber bike frames in comparison to this wishbone...
Thanks Brian,
Beautiful parts! I’m really looking forward to seeing more videos. I also was wondering how long would this part e in service?

Was the 2nd part super finished in a tumbler ??
Media treated yes.
Why after they are installed, they appear to be fixed and as if they cannot be moved.
When machining the thinwall rose joint end how would they dampen the part to control chatter?
a cosa servono quei sensori incollati sul braccio oscillante?
