The natural frequency does not change, however the frequency of the damped system is a function of damping ratio. Wd=sqrt(1-zeta^2)*wn where wS is the frequent the damped system, which mistakenly sometimes is referred to as damped natural frequency, zeta is the damping ratio and an is the natural frequency.

Thank you professor <br><br>I think that the response of constant load must be :<br>U(t)= F./k (cos wn t - 1 )<br>Because the integration of sin is (- cos)

Consider the undamped natural frequency of a single-degree-of-freedom linear <br>spring-mass system. If energy dissipation is added to this system, explain whether the fre- <br>quency of damped vibration will differ from the undamped one, and if so, in what manner?

Professor I will ask you something. Where can I find examples for Duhamel Integral? thanks...
