I came across this formula by Blevins for calculating the natural frequency of a hollow cylinder and was hoping that someone could answer a couple of questions I have. First, here's the formula:
f = A/(2*pi*L^2)*sqrt(E*I/m)
A= 9.87 for first mode
I = Area Moment of Inertia (m^4)
m= Mass per...

Sorry to start a new thread on this but the other one that referenced this topic was closed. In the previous discussion (see above reference post) entitled "Bell modes? for a circular tube" there was mention of a ring frequency formula posted by electricpete where he compared...
