Question 3. The modal equations for a forced 2-degree-of-freedom damped system are given by: äi+2(wiġ+wq = P(t) where: wi 20.7044 rad/s and w 11.3855 rad/s. and Pi(t)=2 cos(4t) and P2(t) = 10 cos(4t) Note that for this problem, proportional damping can be assumed, with: $10.02 and 2 = 0.02 The modal response in the steady-state will be in the form of qi(t) = A, cos(wt - di) Enter your answers for A1, 51 and A2, 62 to four decimal places in the appropriate boxes below: A1: 61: A2: 62:
