Presented here is the solution to the second order differential equation that governs the behavior of the free vibration mode of our apparatus.
If there is no forcing function [F(t) = 0] and the beam is displaced and then released, it experiences a free vibration response. Free vibration is modeled by the Homogeneous Solution to the 2nd Order Differential Equation, which is:
(1) .
The boundary conditions to the homogeneous solution are given by the physical system and are:
(2) .
It can be shown that the solution to the differential equation with the specified boundary conditions is:
(3)
(4) .
