sorry for the trouble, i am working for the theoretical frequency calculation of a SiO2 cantilever with gold coating. I came across a similar paper which has the result given for the resonant frequency of a polysilicon cantilever with gold coating. RESULT: The frequency of polysilicon...

By substituting the values, I got mass = 2.2*10^-8 gm, I=2.08*10^-22 m^4, K=4.56*10^4g/s^2, f= 229KHz . But the expected freq is 82KHz. Pl Check. Thank you for the response. Yes! The gold coating will act like two springs in parallel.

A Cantilever beam of SiO2 of length 100μm, width 20μm and thickness of 5μm. How to calculate the resonant frequency? I know f=1/2∏√(k/m) where k=3EI/L^3 and mass = l*w*h *ρ (density) and I = w*t^3/12, but i don't get the desired answer. pl correct me. What changes are to be considered for...
