SUMMARY
The free resonating frequency of a cantilever beam is determined by its material and geometric properties, and it remains independent of the beam's deflection. The formula for calculating the resonant frequency is given by f = (1/2π) * √(8EI/(ρAl^4)), where I represents the moment of inertia, E is Young's modulus, ρ is the density, A is the cross-sectional area, and l is the length of the beam. This relationship highlights the importance of these parameters in predicting the vibrational characteristics of cantilevers.
