varying load  by GoshDarn Tags: arbitrary, frequency, load,

everyone,  So I have time-varying force data. The force acts as
a concentrated load. The force does not vary
periodically/harmonically, it just has a general variation with
time. My main question is: How do I determine the corresponding
frequency of this force data?  Also, if I'm using MATLAB and I
have a data vector of this force's time variation, how do I use
MATLAB to determine the corresponding frequency data? Do I use
the fft() function?  Any help/insight would be appreciated! Let
me know if you need any more details and I will happily provide
them.  Phys.Org News Partner Physics news on A new, tunable

does not have a single frequency. Do I use the fft() function?
That looks like a Fourier transformation
