Question

se is given by Eq. (E.9) of Example 5.1: 3k (2 (E.8) Comparison of Eqs. (E. 1) and (E.8) shows that the motion of the system coincides with the sec- ond normal mode only if X1-0. This implies that (from Eq. E.2) h(0)=-x2(0) X1(0)=-x2(0) and (E.9) Free-Vibration Response of a Two-Degree-of-Freedom System 5.3 Find the free-vibration response of the system shown in Fig. 5.5(a) with k1 30, k2 5, k30, mi = 10, m2-1, and cl=c2=c3-0 for the initial conditions x1(0)=1, ii(0)= x2(0) 2(0)0

Find the response X1 (t) and X2 (t)
