Question

For the vibration absorber model below. (a) ma is selected to be 5% of main mass m, what should the value of ka be so the vibration of the main mass is eliminated? (b) What are the natural frequencies of the system? (c) Adding a damper to the absorber such that the absorber has a damping ratio of 0.5, how much would the main mass vibrate now? What if the excitation frequency a is equal to each of the system's natural frequencies? F(r) = F0 sin(wt) TI k 2 k/2 Model ω-157.08 rad/s) (m-300 kg; k = 7.402 M ning equations for th
