Vibration forms at 1st–4th modes and the nodal points coordinates at the second (2nd) , third (3rd) , and fourth (4th) resonant oscillation modes of the clamped cantilever with the corresponding virtual acting forces and deflections . Dashed triangles designate virtual supports in the nodal points and circles correspond to virtual positions of additional mass.
Cantilever with length , width , thickness , and additional mass 1 at offset .
The resonant frequency calculated, measured, and simulated for the first four bending modes of the cantilever together with the calculated and experimentally observed change in frequency at the action of additional mass for the specific resonant mode.
