Subject: Flutter speed for rectangular plate (train information display)

Instructions:

1. Set up the quasi-steady equations of motion for a pitching and plunging 2D flat plate.

2. Calculate natural frequency and damping ratio.

3. Plot the variation of the natural frequencies and damping ratios of your system with airspeed.

4. Write a code to determine the flutter speed.

5. Plot the variation of flutter speed with pitch stiffness

Important -

The graphs must be done using Matlab coding (when I put values it gives me the graphs)

It is exactly what I need with two graphs for speed variation vs natural frequency/ damping ration
