Vibration Free
Please, are correct?
Where frequency is
The characteristic equation is:
where
Then:
Calculating I can get
Now, I need to do to get the following equation ?
(I think this is the equation we need to get the free vibration)
It is also a constant (it is the phase) Both and (or if you prefer) are determined by the initial conditions.
What you have is a general solution to a second order ODE, and there should be two constants, these are and in one form of the solution and and in the other form for the solution.
