I'm working on a vibration frequency problem
involving a thin, circular aluminum membrane
with a radius of 0.01m.
I know the volume density of Al.
How do I arrive at a surface density for this circular
membrane -- especially since I'm not given the
thickness (I'm told that frequencies for thin membranes
are independant of thickness).
I could see how to do this if I had a rectangular membrane,
but I have a circular membrane instead.
