A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.
What are those little black boxes at the end of the pushrods secured with two screws? One cable goes to the end of the pushrod, but seems there are no other connection, just some kind of antenna-like protrusion at the other end...looks like some kind of wireless transponder but what should it report/measure?
Strain gauge to measure force on the pushrod (and thus downforce / wheel loads), perhaps?
interesting that, pre-suspended(suspension) force sensor data collection to be calibrated with post-suspended(suspension) data collection, must be in there somewhere..even more interesting if they had laser sensors below the suspension uprights targeted at road surface to measure tyre compression and rebound depth and calibrate frequencies between all that to get an improved set up...maybe tyre pressure sensor is a simpler solution, probably less accurate
A sensor in each upright might be tricky - the uprights are already crowded with other sensors for brake temps etc., as well as the ducting for the air around the brakes. The do run a height sensor under the chassis, however, so they can work out using this and the suspension movement sensors (each corner has a sensor measuring movement) what the various items are doing. For example, if your suspension movement sensor shows a small movement but your chassis height sensor shows a large movement, then you know the tyres are where the difference between those figures is occurring (allowing for any less-than-perfect stiffness in the set up).
Turbo says "Dumpster sounds so much more classy. It's the diamond of the cesspools." oh, and "The Dutch fans are drunk. Maybe"
I may have missed this in other threads and photos:
The way the bell meets up with the inside face of the rotor is new to me, being flush. The rectangular cut-outs in the inner surface of the bell that allow air to enter the rotor are also unusual as there is no geometric relationship to the round cooling holes in the rotor. I wonder what's going on on the outside face of the bell, facing the rotor? Maybe there are pockets formed there?

This isn't new, it's a Brembo development used first by STR. The disc and bell splines are the full thickness of the disc, the bell is pocketed and air passes through the bell into the drillings in the disc. Pictured.
I remember seeing the bell in another shot somewhere but hadn't seen everything mounted up, at least from that inner angle. Your linked images are just what I was asking for.

I think tyre pressure sensors can help to calculate the downforce, but isn't enough. Tire is a not suspended mass and the load on it depends also to the suspension's reaction to the asperities of the track. That sensor assure also to control the movements of suspended masses. Am I wrong?
