and 3.68 By denoting the amplitudes of relative velocity and relative acceleration of the mass of a viscously damped system subjected to a harmonic base motion, y(t), as shown in Fig. 3.14, as z Z Ż and 2, respectively, find expressions for the ratios in terms of r and G. The ż ż nondimensional ratios and are called the relative velocity and relative acceleration 0,Y frequency responses of the mass, respectively. WY wy WY
