(adsbygoogle = window.adsbygoogle || []).push({}); NEMS Resonator

I need a hint to help with my homework.

The question:

"A Si-Based NEMS resonator has dimensions length=150nm, width=5nm and thickness=5nm and an effective spring constant of 100Nm^-1 and natural frequency of vibration of 250MHz"

I am looking for an equation linking the natural frequency to the effective spring constant, as for the first part of the question i have to show what would happen to them if the dimensions of the resonator were doubled.

Any advice, been trawling the net and my notes for a while and no joy.
