I have a problem...I'm calculating natural frequency of a standing cylinder.

In order to do that, I need the k

_{e}- equivalent spring constant of that cylinder.

k

_{e}= (E

_{Y}* s) / (h)

E

_{Y}is Young's elastic modulus for material cylinder's made of

s is the cross section of cylinder

h is the height of cylinder

The cylinder is not considered "very long".

When I find k

_{e}, I don't have any troubles finding the natural frequency.

I just want to know how is this equivalent spring constant derived?

And, is it possible to apply the same approach for other rigid bodies...ie rectangular prism.
