## Main Question or Discussion Point

Hello everyone.

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

In order to do that, I need the k

k

E

s is the cross section of cylinder

h is the height of cylinder

The cylinder is not considered "very long".

When I find k

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.

_{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 ofs 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?
