3.35 Determine the response of the SDF system having m, k and c as the mass,
stiffness and damping due to a periodic force shown in Fig. 3.28.
3.36 Determine the response of an undamped SDF system, subjected to a periodic
loading shown in the figure.
Prob. 3.36
3.37 If the displacement for the support point for a spring–mass system is given in
Fig. 3.30 [change F(t) for x s (t)], determine the relative motion and absolute
motion of the mass.
3.38 Obtain the Fourier series representation of the function given in the figure.
Prob. 3.38
3.39 Determine the response of a spring–mass system having viscous damping
due to the linearly increasing force as shown in the figure.
Prob. 3.39
3.40 An undamped SDF system is subjected to a base acceleration as shown in the
figure. Determine the response spectrum of z.
