WebJul 12, 2024 · I attached several masses to the fixed end of a cantilever beam (a 100 cm ruler) and gave it an initial displacement, causing an oscillation. My experimental data shows a strong correlation between the mass on the fixed end of the cantilever and the period. However, I am not sure how to verify this without a mathematical model. WebThe cantilever dither motion affects the PiF simply because the time-varying tip-sample spacing modulates the intensity and depth of illumination from the tip-enhanced field. Since the illumination source itself is also modulated at f m , frequency mixing produces a sideband component at f 2 −f m = f 1 which thereby induces Q-enhanced ... canada environmental health and safety
