What is the relationship between angle of attack and lift force, and how does this relationship change near the stall point?

Experts please explain this phenomena using relatively easy language but mentioning critical points and formulas. I would really appreciate your explanation due to my desire of understanding how does the wing of the aircraft operate and also want to understand if it will be possible to conduct an experiment using this type of research question

Most people who followed $CYDY remember March 30, 2021. The FDA publicly stated that CytoDyn's claims about leronlimab were "misleading and not supported by the data", no benefit was shown in COVID-19 treatment trials. The stock dropped 25%+ that day.

What happened afterward was a class action lawsuit covering investors who held $CYDY between March 27, 2020 and March 30, 2022.

A $500,000 settlement has been reached and terms are now submitted to the court for approval.

Who qualifies?

Anyone who held $CYDY during the class period and suffered losses from the alleged misrepresentations about leronlimab's effectiveness for HIV and COVID-19.

Can I still apply?

Yes, you can submit your application now and it will be processed once claims filing officially opens after court approval.

If you were damaged by this don't forget to check your eligibility. GL!

Alula - Multi-element and transonic airfoil solver inspired by MSES

Alula uses the Euler + Integral Boundary Layer method to solve for flow around multi-element and transonic airfoils. The method is based on Mark Drela's thesis work that led to the MSES airfoil solver. This is NOT a port of MSES; it was developed independently by pointing Astra toward the relevant literature.

Help with Low Speed Wind Tunnel Force and Pressure Measuring Ideas and Feasibility

Hello, I'm working on a low speed wind tunnel, maximum CSA of 250*250mm with total length of 1.05m, I'm trying to synchronise my idea of having variable wing angle of attack whilst measuring pressure and force like drag and lift.

The idea i researched is using load cells for force, but because my fans are 2 PC fans, the speed isn't high but I have plenty of pressure and airflow.

I also wanted to measure pressure at certain point of the wing or at least before and after the wing and found pressure sensors that you hook up a tube to and that gives pressure differential reading.

Concerns i have is that the calculations i did say that my forces are really low so much that its less than 2grams. I'm not sure on how to proceed or if its even viable.
