SOLVED:A counter-rotating eccentric mass exciter consisting of two rotating 14-oz weights describing circles of 6 -in. radius at the same speed but in opposite senses is placed on a machine element to induce a steady-state vibration of the element and to determine some of the dynamic characteristics of the element. At a speed of 1200 rpm, a stroboscope shows the eccentric masses to be exactly under their respective axes of rotation and the element to be passing through its position of static equ

7-F) A variable-speed counter-rotating eccentric-weight exciter is attached to a machine to determine its natural frequency. With the exciter at 1,000 rpm, a stroboscope shows that the eccentric weights of the exciter are at the top the instant the machine is moving upward through its static equilibrium position. The amplitude of the displacement is 12 mm. The mass of the machine is 500 kg and that of the exciter is 20 kg with an unbalance of 0.1 kg-m. Find (a) the natural frequency and the damp
