Define a sinusoidally varying load

Define a sinusoidally varying load

(OP)
Dear all!

I have been hunted by this question for a long time. Wish I could have the luck to get some helps from here. Thanks in advance!

I'm analysing a structure's dynamic response due to a sinusoidally varing force. The force is like:

                  F=sin(wt)

But the 'w' here needs to vary from 0 to 1000 Hz.
Finally what I want is a digram that Y-axis is the displacement of a certain node, and X-axis is the Frequency of the load from 0 to 1000 Hz.

Thanks A LOT !
