St rol In crns (section 6.4) 19-25 the steady-state response of the mechanical system shown in Figure P19-p25 is sought. The systenm problems arameter values m-l, b-0.1, k -20, in consistent units, and is subjected to a periodic applied force f .Note that when this system is subjected to F cos ot, the steady-state response is exactly as in Eq. (3.30) of Section 3,4, with the sine function replaced by the cosine function! 19 )-sin 2 f(t)-2 21 f)-20 cos 5t -sin nt n n=1,3,5 22 ft)- sin 2t +cos 23 2/x) 凸f(t) = 2(1-1), 0 1 π , definition in one period one 0<1<2, definition in one period! moriodl
