It's just that the inertia goes with the cube of the section height, making it rather difficult to compensate for with wall thickness alone.

Bur take a closer look at that "reinforcement rope" and read my posts from today and think about it.

+1 I go with the swede.

the point is : we SEE bending in that area ,don´t we? so when section thickness is small in that area it may not be the only reason for the bending ,but that was not my claim anyways.But still it will potentially help to bend in exactly this area.

Maybe the end of the tub has a heat expandable spacer,transfer rods move the heat from the brakes to the spacer causing expansion and tilting the nose down and back and in turn exaggerating the load to the wing to run it lower. A small amount of movement here will be more at the wing itself through the angles of the nose and mounting.

Just a theory!

Precisely. Everyone knows that Newey has the power to bend things with his mind. Why else is he so valuable? Why else would they have him on the pit wall?

If you look carefully during some of the RBR pitstops, you can at times see Newey's hand browsing the bodywork,
a bending-blessing or simply the hand of God?

But seriously, I am quite confident that the early on supected anisotropic material created by funny carbon-fibre layups will be xplained by that crocked reinforcement "rope", differentiating the FIA-loadcase from reality.

Yeah, it would be outright presumptious to doubt the man, wouldn't it?

Look Pup, that reinforcement-rope is shaped like a crank, a smoking gun if anyone would ever ask me.

You'll have to explain this rope thing to me. I have no idea what you're looking at.

Scroll back a few pages Pup, look at the pictures an read my humble analysis of that carbofibre thing.

I don't see what you're calling a 'rope'. Crank-shaped nor smoking-gun shaped.

But Looking at the photo again, another idea, similar to my first, would be to bull the inner connection of the second element down so that it in line with the first. The new geometry would be easier to bend. It could be done using a cam, powered, or perhaps the forces acting to twist the wing would move it enough that it popped in place. The net result is the same as my first idea, but this way there is never a gap.

Perhaps that's similar to what you're saying? You're pulling that bit of the second element back (right?) whereas I'm pulling it down.

I´m not 100% sure whatxpensive means with the "rope or worm" but if we mean the same, then it is this.

IMO there is not really a wing A and wing B, by the look of it the main wing (A) is sloted,
what xpensive descripts as "rope" is IMO the leading edge of the upper section of the main wing A ( some will call this wing B).

It looks to me, like a "prebend-structure". bended upwards.
Element C (the one which generates the most drag/horizontal force could be used to straighten this prebend out by pulling the middle section up via the support/connection.
Notice thst the strong black carbon bracket wich supports the element C (flap) joins more or less ecxactly the upper element of the main plane (B) where it is bend the most.

If you look at the photos when the wing is not in motion (pitlane) you can see that this part is bend upwards. In the photos which shows the car in motion, and the wing bending, this section appears to be straight IMO.

But maybe I start seeing things ( unicorns :P ) - it´s well possible

I try to capture it here, but the quality is not that great - sorry

From everywhich angle you look, there is a rope-like structure in place between sections A and B, which are actually in one piece if you look closer to the end-plate. Looking from a top-view, this "rope" is crooked with a lever-shape, mening that a load center ahead of said lever will bent the front wing upwards, while a load-center behind (like in reality) will bend the wing down.

Took me a while as well to see this.

I just see the unpainted leading edges of the wing elements. I must not be looking at the right pieces.

747, I see what you say, and I see what the "architect's view" (that cracks me up) is saying. And I'm sure that the teams all factor the twisting of the wings unto their calcs. But when I look at the pics of the wing at speed, and the videos, it looks to me like the wing is bending considerably right where it joins the FIA section. Other wings look to bend evenly across their length, as you'd expect. That's why I think something fishy might be going on at that point, and the odd connection of the "2nd" element makes me wonder more. .
