Energy analysis of forced spring mass damper system
Here I derive expressions for the energy added per cycle due to both the harmonic excitation force and the damper. The work done by the spring per cycle = 0.

Spring Mass system Proof
A mass that is connected to a spring will undergo simple harmonic motion. This means it's Equation of Motion is
x = A sin (w_n t + phi_1) where w_n =
(k/m)^1/2
Note that w_n is the frequency of oscillation...

logarithmic decrement proof
Here I derive the formula used for logarithmic decrement. This is way to experimentally determine the values of your damping ratio. To do it:

peak
2) Find delta...
