Question 3. The modal equations for a forced 2-degree-of-freedom damped system are given by: ö: +26wiġi +w?qi = P (t) where: w 18.1839 rad/s and w, = 13.0026 rad/s. and P (t) = 23 cos(9t) and P,(t) = 6 cos(9t) Note that for this problem, proportional damping can be assumed, with: 61 = 0.07 and C2 = 0.06 The modal response in the steady-state will be in the form of 9:(t) = A cos(wt - 0) Enter your answers for A1,8, and A2,8, to four decimal places in the appropriate boxes below: A: 8: A2: 82: 1
