For a system with an undamped natural frequency of 100 Hz and a damping ratio of 0.05, what is the maximum frequency of excitation below the natural frequency where the transmitted force is no greater than 110% of the static value? What is the minimum frequency that meets this condition above the natural frequency?
A bob (small ball) is attached to the lower end of a cord that is attached to the cieling and moves in a horizontal circle at a constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.040 kg, the cord has a length ..
