When the car is cool in the FIA test, the wing deforms according the rules. I know there was a rumor that RB was doing something similar in the past with the floor splitter during their V8 dominance.
It’s not about heat... The rear wing would be 100% rigid if they wanted to... It is the materials used in the construction, the teams have knowledge and ability to include in the design a non-linear movement under load... Meaning that the wing bends “X” in linear way until a certain weight and then bends “Y” in a different ratio after that weight... Therefore passing the static test.

Yeah, but can’t you use the heat to achieve this effect?
Heat from where? Look where the exhaust pipe is and the direction of the air as it moves over the car. Pretty much impossible.
What they are doing to achieve the bending is quite simple actually. Take for example your legs. You can stand up straight and your knees wont bend. That is all 200 pounds of you or whatever you weigh. But if a friend pushes the back of your knee while you stand, it will bend easily even when under you weight. Simple mechanics.
