Summer Exam #2

On the cheat sheet as well as a couple of example problems there is the equation Ft=Xω
(2)n * sqrt(1+(2ζr)
2). I am confused because from what I understand Ft is the amplitude of the transmitted FORCE, but yet if I am not mistaking the units for this equation do not work out to be Newtons. Is this equation missing “mass”?
