Module 6: Mechanical Vibrations

20267m

A single-degree damped vibrating system has mass 7.5 kg and makes 24 free oscillations in 14 seconds. The amplitude reduces to 0.25 of its initial value after five oscillations. Determine (i) spring stiffness, (ii) logarithmic decrement, and (iii) damping factor (system damping/critical damping).
