You can adjust the driving frequency, f in \text{Hz}, of the shaking mechanism, the amplitude of the driving force, F_{o}, in Newtons, the amount of friction, b in \text{Ns/m}, and...You can adjust the driving frequency, f in \text{Hz}, of the shaking mechanism, the amplitude of the driving force, F_{o}, in Newtons, the amount of friction, b in \text{Ns/m}, and the stiffness of the springs, κ, measured in \text{N/m}. In the previous simulation we saw that the natural frequency, written as f_{o} is given by the stiffness of the spring, κ, and the mass; f_{o} = (κ/m)^{1/2}/(2π).
