Why does your steering wheel feel like it wants to straighten out when you're in a turn? In this video, I'll explain what aligning torque is, and where it comes from.
===== NOTES =====
► I'm not including any mechanical trail in this description.
► The tire has no inclination angle/camber.

This is the first video in my 10-video series on coding a program in MATLAB to compute, display, and save a NACA 4-digit airfoil. The series starts right from the beginning, and we work our way to the final code. I explain everything I do, so it should be easy to follow.
IN THIS VIDEO:
We start by opening up a new graphical user interface by typing guide in the command window, and lay out our GUI buttons, boxes, etc. After saving the GUI, we format the resulting m-file for ease of coding in the subsequent videos.
If you havent watched my other videos on the NACA 4-digit airfoil series, I would recommend doing that now.

Axes can be used to display data on a plot, or even to display an image. This video shows how to display a plot with data in a MATLAB GUI.")

A waitbar (or progress bar) allows you to visualize when a program will finish. The argument to the waitbar fills up the bar with the percentage specified. While its a fun way to see how long you have to wait until everything is done computing, it is extremely time consuming, and I would probably recommend just outputting data to the command window using fprintf.")

This is the last video in my 10-video series on coding a program in MATLAB to compute, display, and save a NACA 4-digit airfoil.
IN THIS VIDEO:
We add in the code for saving the airfoil data out to a text file. Both the LE to TE and TE to LE methods are coded. A comparison between the output from this code and the data from the UIUC airfoil data site (see link below) is made to confirm that our code works the way it should.
