Fixed-Free-Fixed-Free Plate, Fundamental Vibration Mode

The plate is aluminum, 0.063 inch thick.  The fixed edge length is 6 inch.  The free edge length is 4 inch.

The vibration mode was calculated via the Rayleigh method using an assumed displacement function, as carried out via Matlab script:  fixed_free_fixed_free_plate.m

The method is given in:  fixed_free_fixed_free_plate.pdf
