The formula for the amplitude of a forced vibration depends on the system's properties and the driving frequency. For a simple harmonic motion (SHM), the amplitude can be calculated using the equation A = F0 / (m * ω^2), where A is the amplitude, F0 is the driving force, m is the mass, and ω is the angular frequency.

Screen Motion. The processes of particle stratification and probability are caused by the vibration of the screen. On inclined screens, the vibration is caused by a circular motion in a vertical plane of 1/8 to 1/2- inch amplitude at 700 to 1000 cycles/min. The vibration lifts the particles up, thereby, causing stratification.
